query: American Idiot is a Green Day album.

pos: American Idiot American Idiot is the seventh studio album by American rock band Green Day . Produced by Rob Cavallo , the album was released in the UK on September 20 , 2004 and in the US on September 21 , 2004 by Reprise Records . Green Day first achieved popularity in the 1990s with a string of successful albums . Following disappointing sales of their sixth album , Warning ( 2000 ) , the band took a break before recording their next album , titled Cigarettes and Valentines . The recording process was cut short when the album 's master tapes were stolen . Rather than re-record that material , the group decided to start over .   A concept album and the world 's first `` punk rock opera , '' American Idiot follows the story of Jesus of Suburbia , an adolescent anti-hero who is divided between `` rage and love . '' Through its plot , the album expresses the disillusionment and dissent of a generation that came of age in a period shaped by many tumultuous events like the Iraq War . The album was inspired by several musicals and the work of The Who . Recording of American Idiot was split between two California studios between 2003 and 2004 . Its album art depicts a heart-shaped hand grenade .   American Idiot marked a career comeback for Green Day following a period of decreased success . It charted in 27 countries , peaking at number one in 19 , and eventually sold 16 million copies worldwide . The album spawned five successful singles : `` American Idiot '' , `` Boulevard of Broken Dreams '' , `` Holiday '' , `` Wake Me Up When September Ends '' and `` Jesus of Suburbia '' . American Idiot was well received critically and won the Grammy Award for Best Rock Album in 2005 . Its success inspired a Broadway musical and an incomplete feature film adaptation . It has been praised in the years following its release , appearing on several year-end and decade-end lists .

PAX AM Days was the band 's second release in 2013 after the comeback album Save Rock and Roll , and marks a return to their hardcore musical roots with aggressive guitar work , the `` antithesis '' to the polished Save Rock and Roll .   Adams reached out to the group at the request of Fall Out Boy 's friend and collaborator Butch Walker . Bassist Pete Wentz commented `` I think there 's a side of our band in our fans that would appreciate some of the noise that Ryan comes up with , and it would be great for the fans to be able to hear that -- hear sort of the raw energy that happens from sessions like that .

Idiotarods take place in Ann Arbor , Asheville , Austin , Boston , Chicago , Cincinnati , Dallas , Denver , Iowa City , New York City , Phoenix , Portland , Salt Lake City , Seattle , St. Louis , Toronto , Los Angeles , Vancouver and Washington , D.C. though the original race was founded in San Francisco in 1994 as the `` Urban Iditarod '' .

neg: An American Prayer An American Prayer is the ninth and final studio album by the Doors . In 1978 , seven years after lead singer Jim Morrison died and five years after the remaining members of the band broke up , Ray Manzarek , Robby Krieger , and John Densmore reunited and recorded backing tracks over Morrison 's poetry ( originally recorded in 1969 and 1970 ) . Other pieces of music and spoken word recorded by the Doors and Morrison were also used in the audio collage , such as dialogue from Morrison 's film HWY : An American Pastoral and snippets from jam sessions .   Despite managing a RIAA platinum certification in the US , the album received mixed reviews and still divides critics . When the album was originally released , longtime Doors ' producer Paul A. Rothchild labeled the album a `` rape of Jim Morrison . '' Rothchild claimed that he had heard all of the reels of master tapes from both the 1969 and the 1970 poetry sessions , insisting that the three remaining Doors failed to realize Morrison 's original intent for an audio presentation of the poetry . Prior to leaving for Paris , Morrison had approached composer Lalo Schifrin as a possible contributor for the music tracks meant to accompany the poetry , with no participation from any of the other Doors members . Additionally , he had developed some conception of the album cover art work by January 1971 , and was in correspondence with artist T. E. Breitenbach to design this cover in the form of a triptych . However , John Haeny ( who recorded the original session tapes with Morrison in 1970 and safeguarded them before the project was resurrected as An American Prayer ) insisted that the album `` was made by those people who were closest to Jim , both personally and artistically '' and `` everyone had the best intentions , '' stating : `` Jim would be pleased . Jim would have understood our motivation and appreciated our dedication and heartfelt handling of his work . ''   The album also includes a composite live version of `` Roadhouse Blues , '' splicing together performances at New York City 's Felt Forum and Detroit 's Cobo Hall , both captured during the Doors ' 1970 Roadhouse Blues Tour . This version of the song later appeared on the In Concert compilation .

neg: How Sweet to Be an Idiot How Sweet To Be An Idiot is the first solo album by Neil Innes , formerly of The Bonzo Dog Band and later of The Rutles , and was released in 1973 . Innes later said of this time   Stewart Mason , reviewing the album for Allmusic , described it as `` split between tongue-in-cheek parody and straight pop songs '' and containing `` solidly melodic Beatlesque pop '' , but was critical of the `` unfortunate sterility to Innes ' self-production '' .   The title track was released as a single but failed to chart . It was a more instrumented version than on the album , arranged by Richard Hewson , and `` The Age of Desperation '' was the B-side . Its melody was borrowed by Oasis for their single `` Whatever '' , released in 1994 ; Innes claimed plagiarism and as a result now receives royalties and a co-writing credit .   The album was re-released by United Artists in 1980 under the title `` Neil Innes A-Go-Go '' and by EMI in 1994 with additional tracks -- most of which had been released on singles -- under the title Re-Cycled Vinyl Blues . This edition of the album was dedicated to Ollie Halsall , who had died in 1992 , and former Bonzo Dog bassist Dennis Cowan , who had died in 1972 ; it featured a guest appearance by Michael Palin on the title track .   A review of the release by Mark Deming of Allmusic was more appreciative than that of his predecessor , saying that `` most -LSB- of the tracks -RSB- walk a graceful tightrope between sly humor and solid pop-friendly rock & roll '' and recommending that `` anyone who digs a great hook played with heart should get to know the music of Neil Innes '' .   Innes performed the title song on Monty Python Live at the Hollywood Bowl and on Monty Python Live at Drury Lane .

neg: Warning (Green Day album) Warning ( stylized as WARNING :) is the sixth studio album by American punk rock band Green Day , released on October 3 , 2000 by Reprise Records . Building upon its predecessor , Nimrod ( 1997 ) , the album eschewed the band 's trademark punk rock sound and incorporated acoustic elements and pop and folk styles . Lyrically , the record contains more optimistic and inspirational themes in comparison with the band 's earlier releases . Warning was also Green Day 's first album since Kerplunk ( 1992 ) that was not produced by Rob Cavallo , although he did have a hand in its production and was credited as executive producer .   Despite mixed criticism towards the band 's stylistic change , the album received mostly positive reviews from music critics , who praised vocalist/guitarist Billie Joe Armstrong 's songwriting . Although it peaked at number four on the US Billboard 200 chart , Warning represented the lowest commercial slump in Green Day 's career , being the band 's first album since signing to a major record label not to achieve multi-platinum status . The album has nonetheless been certified platinum by the Recording Industry Association of America and , as of December 2012 , has sold 1.2 million copies . Warning was reissued on vinyl on July 14 , 2009 .

query: Venus has an atmosphere consisting of carbon dioxide.

pos: Venus Venus is the second planet from the Sun , orbiting it every 224.7 Earth days . It has the longest rotation period ( 243 days ) of any planet in the Solar System and rotates in the opposite direction to most other planets . It has no natural satellites . It is named after the Roman goddess of love and beauty . It is the second-brightest natural object in the night sky after the Moon , reaching an apparent magnitude of − 4.6 , bright enough to cast shadows at night and , though rare , occasionally be visible in broad daylight . Because Venus orbits within Earth 's orbit it is an inferior planet and never appears to venture far from the Sun ; its maximum angular distance from the Sun ( elongation ) is 47.8 ° .   Venus is a terrestrial planet and is sometimes called Earth 's `` sister planet '' because of their similar size , mass , proximity to the Sun , and bulk composition . It is radically different from Earth in other respects . It has the densest atmosphere of the four terrestrial planets , consisting of more than 96 % carbon dioxide . The atmospheric pressure at the planet 's surface is 92 times that of Earth , or roughly the pressure found 900 m underwater on Earth . Venus is by far the hottest planet in the Solar System , with a mean surface temperature of 735 K , even though Mercury is closer to the Sun . Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid , preventing its surface from being seen from space in visible light . It may have had water oceans in the past , but these would have vaporized as the temperature rose due to a runaway greenhouse effect . The water has probably photodissociated , and the free hydrogen has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field . Venus 's surface is a dry desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism .   As one of the brightest objects in the sky , Venus has been a major fixture in human culture for as long as records have existed . It has been made sacred to gods of many cultures , and has been a prime inspiration for writers and poets as the `` morning star '' and `` evening star '' . Venus was the first planet to have its motions plotted across the sky , as early as the second millennium BC .   As the closest planet to Earth , Venus has been a prime target for early interplanetary exploration . It was the first planet beyond Earth visited by a spacecraft ( Mariner 2 in 1962 ) , and the first to be successfully landed on ( by Venera 7 in 1970 ) . Venus 's thick clouds render observation of its surface impossible in visible light , and the first detailed maps did not emerge until the arrival of the Magellan orbiter in 1991 . Plans have been proposed for rovers or more complex missions , but they are hindered by Venus 's hostile surface conditions .

neg: Modern Mars habitability One of the central questions of modern Astrobiology is whether there is , or ever has been life on Mars . Mars probably had oceans in the past , and it definitely had lakes and a thicker atmosphere . Modern Mars has become cold , dry , and almost uninhabitable , yet , if life did ever arise on Mars , some hardy microbes and perhaps even multicellular life might survive there right through to the present . The only missions to search for life on Mars , the two Viking missions , returned results that were inconclusive  . However the instruments were not designed to cope with the unusual conditions which Viking discovered on Mars , which may have confused the results of the experiments . Also , they did n't know enough about Mars at that time to target the regions we now think are most likely to have present day life .   Life would meet many challenges on present day Mars . Liquid water boils at 0 ° C , over much of its surface . Even at the depths of the Hellas basin , any water is close to its boiling point of 10 ° C and will dry out quickly . Ice also evaporates into the atmosphere over geological timescales - and most of the equatorial regions are thought to be dry to depths of tens of meters . As its axial tilt varies , Mars atmosphere is sometimes thicker , and liquid water may then form on the surface - but any dormant life in the top few meters of soil would be destroyed over periods of millions of years by cosmic radiation .   However , in 2008 , droplets were observed on the landing legs of Phoenix . Sadly , there was no way to analyse them , but the leading hypothesis is that they were droplets of salty water . Phoenix also made isotopic measurements which show that the Mars atmosphere has exchanged oxygen molecules with liquid on the surface in the recent geological past . This could indicate either recent episodic occurrences of liquid water ( for instance after a meteorite strike ) or water present every year , in contact with the atmosphere .   We now know of many seasonal changes in the surface of Mars which are only visible in high resolution photographs . Most of these are now thought to be caused by dry ice or wind effects . However , the `` Recurrent slope lineae '' , and some of the `` flow like features '' form in conditions that suggest the occasional presence of small quantities of water on Mars . The evidence of flowing brines in the RSLs is strong , though it 's not known if they are habitable . Curiosity has also found indirect evidence of a brine layer 15 cm below the sands that it drives over , though most scientists think that this layer is not habitable for Earth life . Recent Mars surface simulations by Nilton Renno and his team have shown that small droplets of water can form on salt / ice interfaces for a few hours per day almost anywhere on the surface of Mars , and this may explain the Phoenix leg droplets observations .   In a separate development , research by the German aerospace company DLR in Mars simulation chambers and on the ISS show that some Earth life can survive simulated Mars surface conditions without any water at all , and photosynthesize and metabolize , slowly . It can do this using the high relative humidity of the Mars atmosphere at night . All of this work was done after the Phoenix discoveries in 2008 .   Other potential habitats include lakes formed in the higher latitudes after cometary or meteorite impacts , or as a result of volcanism . Covered by ice , these may remain liquid for centuries , or up to a few thousand years for the largest impacts . The planet may also have underground trapped layers of water heated by geothermal hotspots . Also there are suggestions that Mars may have a deep hydrosphere , a liquid layer below its cryosphere , a few kilometers below the surface . Deep rock habitats on Earth are inhabited by life so if this layer exists , it may also be habitable on Mars .   The main questions are   Do these potential habitats exist ?  Are they habitable ? For instance , liquid water , if present , could be too cold , or too salty for Earth life  Are they in fact inhabited by any forms of life ? As Mars is so inhospitable , life might not be able to spread to new habitats easily . So there might be life in some of the habitats and not in others . Or life on Mars may have gone extinct , or never evolved at all , in which case none of the habitats would be inhabited .   These discoveries have renewed interest in this topic , with many astrobiologists saying that they think present day Mars may be more habitable than previously thought . The first conference on the Present Day Habitability of Mars was held in 2013 in UCLA . The 2017 conference session on Modern Mars Habitability will run from April 24 -- 28 in Mesa , Arizona

neg: Gas exchange Gas exchange is the biological process by which gases move passively by diffusion across a surface . Typically , this surface is - or contains - a biological membrane that forms the boundary between an organism and its extracellular environment .   Gases are constantly consumed and produced by cellular and metabolic reactions in most living things , so an efficient system for their exchange is required . Smaller organisms , such as bacteria , have a high surface-area to volume ratio . In these unicellular organisms , the external boundary of the organism - typically the cell membrane - is usually sufficient for the necessary gas exchange . Some small multicellular organisms , such as flatworms , are also able to perform sufficient gas exchange across the skin or cuticle that surrounds their bodies . However , in most larger organisms , which have a small surface-area to volume ratio , specialised structures with convoluted surfaces such as gills , pulmonary alveoli and spongy mesophyll provide the additional area needed for effective gas exchange . These convoluted surfaces may sometimes be internalised into the body of the organism : this is the case for alveoli , which form the inner surface of the mammalian lung ; spongy mesophyll , which is found inside the leaves of some kinds of plant ; and the gills of those molluscs that have them , which may be found in the mantle cavity .   In aerobic organisms , gas exchange is particularly important for respiration , which involves the uptake of oxygen and release of carbon dioxide . Conversely , in oxygenic photosynthetic organisms such as most land plants , uptake of carbon dioxide and release of both oxygen and water vapour are the main gas-exchange processes occurring during the day . Other gas-exchange processes are important in less familiar organisms : e.g. carbon dioxide , methane and hydrogen are exchanged across the cell membrane of methanogenic archaea ; nitrogen is exchanged in denitrifying and nitrogen fixing bacteria ; and hydrogen sulfide and other gases are exchanged in giant tube worms .

neg: Corrosion in space Corrosion in space is the corrosion of materials occurring in outer space . Instead of moisture and oxygen acting as the primary corrosion causes , the materials exposed to outer space are subjected to vacuum , bombardment by ultraviolet and X-rays , and high-energy charged particles ( mostly electrons and protons from solar wind ) . In the upper layers of the atmosphere ( between 90 -- 800 km ) , the atmospheric atoms , ions , and free radicals , most notably atomic oxygen , play a major role . The concentration of atomic oxygen depends on altitude and solar activity , as the bursts of ultraviolet radiation cause photodissociation of molecular oxygen . Between 160 and 560 km , the atmosphere consists of about 90 % atomic oxygen .

neg: The Wizard of Venus `` The Wizard of Venus '' is a novella by Edgar Rice Burroughs , as well as the title of a collection in which it was later published together with an unrelated story . `` The Wizard of Venus '' is the final story in Burroughs 's Venus series ( sometimes called the `` Carson Napier of Venus series '' ) . Written in 1941 , the piece remained unpublished until 1964 , fourteen years after the author 's death . Burroughs intended it to be the opening piece in a sequence of stories to be brought together later in book form , as he had done in the instance of the previous Venus volume , Escape on Venus . He began the first follow-up tale , only to abandon the project in the wake of the Japanese attack on Pearl Harbor ; the text of the aborted sequel is now lost .   `` The Wizard of Venus '' was first published in the 1964 Burroughs collection Tales of Three Planets together with the unrelated tales `` The Resurrection of Jimber-Jaw '' , `` Beyond the Farthest Star '' and `` Tangor Returns '' . Afterwards it appeared in the collection The Wizard of Venus ( Ace Books , August 1970 ) . This also included the unrelated pirate adventure `` Pirate Blood '' - with a quite unsavory `` hero '' - Johnny LaFitte of Glenora , California - a 20th-century descendant of Jean Lafitte who gets to the distant Vulture 's Island , where his pirate heredity asserts itself in a modern piratical career full of cold-blooded murders and rapes .   A subsequent British edition ( New English Library , 1975 ) omitted the unrelated story .

neg: Carbon leakage Carbon leakage occurs when there is an increase in carbon dioxide emissions in one country as a result of an emissions reduction by a second country with a strict climate policy .   Carbon leakage may occur for a number of reasons :  if the emissions policy of a country raises local costs , then another country with a more relaxed policy may have a trading advantage . If demand for these goods remains the same , production may move offshore to the cheaper country with lower standards , and global emissions will not be reduced .  if environmental policies in one country add a premium to certain fuels or commodities , then the demand may decline and their price may fall . Countries that do not place a premium on those items may then take up the demand and use the same supply , negating any benefit .   There is no consensus over the magnitude of long-term leakage effects . This is important for the problem of climate change .   Carbon leakage is one type of spill-over effect . Spill-over effects can be positive or negative ; for example , emission reductions policy might lead to technological developments that aid reductions outside of the policy area .   `` Carbon leakage is defined as the increase in emissions outside the countries taking domestic mitigation action divided by the reduction in the emissions of these countries . '' It is expressed as a percentage , and can be greater or less than 100 % .   Carbon leakage may occur through changes in trading patterns , and that is sometimes measured as the balance of emissions embodied in trade ( BEET ) .

neg: Hypothetical types of biochemistry Hypothetical types of biochemistry are forms of biochemistry speculated to be scientifically viable but not proven to exist at this time . The kinds of living organisms currently known on Earth all use carbon compounds for basic structural and metabolic functions , water as a solvent , and DNA or RNA to define and control their form . If life exists on other planets or moons , it may be chemically similar ; it is also possible that there are organisms with quite different chemistries -- for instance involving other classes of carbon compounds , compounds of another element , or another solvent in place of water .   The possibility of life-forms being based on `` alternative '' biochemistries is the topic of an ongoing scientific discussion , informed by what is known about extraterrestrial environments and about the chemical behaviour of various elements and compounds . It is also a common subject in science fiction .   The element silicon has been much discussed as a hypothetical alternative to carbon . Silicon is in the same group as carbon on the periodic table and , like carbon , it is tetravalent , although the silicon analogs of organic compounds are generally less stable . Hypothetical alternatives to water include ammonia , which , like water , is a polar molecule , and cosmically abundant ; and non-polar hydrocarbon solvents such as methane and ethane , which are known to exist in liquid form on the surface of Titan .

neg: Martian polar ice caps The planet Mars has two permanent polar ice caps . During a pole 's winter , it lies in continuous darkness , chilling the surface and causing the deposition of 25 -- 30 % of the atmosphere into slabs of CO2 ice ( dry ice ) . When the poles are again exposed to sunlight , the frozen CO2 sublimes , creating enormous winds that sweep off the poles as fast as 400 km/h . These seasonal actions transport large amounts of dust and water vapor , giving rise to Earth-like frost and large cirrus clouds . Clouds of water-ice were photographed by the Opportunity rover in 2004 .   The caps at both poles consist primarily of water ice . Frozen carbon dioxide accumulates as a comparatively thin layer about one metre thick on the north cap in the northern winter only , while the south cap has a permanent dry ice cover about 8 m thick . The northern polar cap has a diameter of about 1000 km during the northern Mars summer , and contains about 1.6 million cubic km of ice , which if spread evenly on the cap would be 2 km thick . ( This compares to a volume of 2.85 million cubic km ( km3 ) for the Greenland ice sheet . ) The southern polar cap has a diameter of 350 km and a thickness of 3 km . The total volume of ice in the south polar cap plus the adjacent layered deposits has also been estimated at 1.6 million cubic km . Both polar caps show spiral troughs , which recent analysis of SHARAD ice penetrating radar has shown are a result of roughly perpendicular katabatic winds that spiral due to the Coriolis Effect .   The seasonal frosting of some areas near the southern ice cap results in the formation of transparent 1 m thick slabs of dry ice above the ground . With the arrival of spring , sunlight warms the subsurface and pressure from subliming CO2 builds up under a slab , elevating and ultimately rupturing it . This leads to geyser-like eruptions of CO2 gas mixed with dark basaltic sand or dust . This process is rapid , observed happening in the space of a few days , weeks or months , a rate of change rather unusual in geology -- especially for Mars . The gas rushing underneath a slab to the site of a geyser carves a spider-like pattern of radial channels under the ice .

neg: Tetravalence In chemistry , a tetravalence is the state of an atom with four electrons available for covalent chemical bonding in its valence ( outermost electron shell ) . An example is methane ( CH4 ) : the tetravalent carbon atom forms a covalent bond with four hydrogen atoms . The carbon atom is called tetravalent because it forms 4 covalent bonds .  A carbon atom has a total of six electrons occupying the first two shells , i.e. , the K-shell has two electrons and the L-shell has four electrons . This distribution indicates that in the outermost shell there are one completely filled 's ' orbital and two half-filled ` p ' orbitals , showing carbon to be a divalent atom . But in actuality , carbon displays tetravalency in the combined state . Therefore , a carbon atom has four valence electrons . It could gain four electrons to form the C4 − anion or lose four electrons to form the C4 + cation . Both these conditions would take carbon far away from achieving stability by the octet rule . To overcome this problem carbon undergoes bonding by sharing its valence electrons . This allows it to be covalently bonded to one , two , three or four carbon atoms or atoms of other elements or groups of atoms . Let us see how carbon forms the single , double and triple bonds in the following examples .   A carbon atom has four electrons in its outermost valence shell . So , it needs four more electrons to complete its octet . A carbon atom completes its octet only by sharing its valence electrons with other atoms . As a result , a carbon atom forms four covalent bonds by sharing valence electrons with other atoms . This is known as tetravalency of carbon ( `` tetra '' means four ) . These four valences of carbon are directed towards four corners of a tetrahedron , and inclined to each other atomic an angle of a 109 ° 28 ´ .   The carbon atom is assumed to be atomic the center of the tetrahedron . In common use , the four valences of carbon are shown by four bonds around a carbon atom as shown alongside   Methane molecule : Each carbon atom has four electrons in its outermost shell . Thus , it requires four more electrons to acquire a stable noble gas configuration . Each of the hydrogen atoms has only one electron in its outermost shell and requires one more electron to complete its outermost shell ( to acquire He configuration ) . To achieve this , one carbon atom forms four single covalent bonds with four hydrogen atoms .   Carbon dioxide molecule : Each carbon atom has four electrons in its outermost shell and each oxygen atom has six electrons in its outermost shell . Thus , each carbon atom requires four , and each oxygen atom requires two more electrons to acquire noble gas configurations . To achieve this , two oxygen atoms form a double covalent bond with carbon .   Acetylene molecule : Each carbon atom has four electrons in its outermost shell and each hydrogen atom has only one electron in its outermost shell . Two carbon atoms share two electrons each with hydrogen atoms to form single bonds . Each carbon then requires three more electrons to acquire a stable configuration of the nearest noble gas ( neon ) . This is done by mutually sharing three pairs of electrons between the two carbon atoms to form a triple bond .   Category : Chemical properties

neg: Kepler (spacecraft) Kepler is a space observatory launched by NASA to discover Earth-size planets orbiting other stars . Named after astronomer Johannes Kepler , the spacecraft was launched on March 7 , 2009 , into an Earth-trailing heliocentric orbit .   Designed to survey a portion of our region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and estimate how many of the billions of stars in the Milky Way have such planets , Kepler sole scientific instrument is a photometer that continually monitors the brightness of over 145,000 main sequence stars in a fixed field of view . These data are transmitted to Earth , then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star .   Kepler is part of NASA 's Discovery Program of relatively low-cost , focused primary science missions . The telescope 's construction and initial operation were managed by NASA 's Jet Propulsion Laboratory , with Ball Aerospace responsible for developing the Kepler flight system . The Ames Research Center is responsible for the ground system development , mission operations since December 2009 , and scientific data analysis . The initial planned lifetime was 3.5 years , but greater-than-expected noise in the data , from both the stars and the spacecraft , meant additional time was needed to fulfill all mission goals . Initially , in 2012 , the mission was expected to be extended until 2016 , but on July 14 , 2012 , one of the spacecraft 's four reaction wheels used for pointing the spacecraft stopped turning , and completing the mission would only be possible if all other reaction wheels remained reliable . Then , on May 11 , 2013 , a second reaction wheel failed , disabling the collection of science data and threatening the continuation of the mission .   On August 15 , 2013 , NASA announced that they had given up trying to fix the two failed reaction wheels . This meant the current mission needed to be modified , but it did not necessarily mean the end of planet hunting . NASA had asked the space science community to propose alternative mission plans `` potentially including an exoplanet search , using the remaining two good reaction wheels and thrusters '' . On November 18 , 2013 , the K2 `` Second Light '' proposal was reported . This would include utilizing the disabled Kepler in a way that could detect habitable planets around smaller , dimmer red dwarfs . On May 16 , 2014 , NASA announced the approval of the K2 extension .   , Kepler and its follow-up observations had found 1,013 confirmed exoplanets in about 440 star systems , along with a further 3,199 unconfirmed planet candidates . Four planets have been confirmed through Kepler K2 mission . In November 2013 , astronomers estimated , based on Kepler space mission data , that there could be as many as 40 billion rocky , Earth-size exoplanets orbiting in the habitable zones of Sun-like stars and red dwarfs within the Milky Way . It is estimated that 11 billion of these planets may be orbiting Sun-like stars . The nearest such planet may be 12 ly away , according to the scientists .   On January 6 , 2015 , NASA announced the 1,000 th confirmed exoplanet discovered by the Kepler Space Telescope . Four of the newly confirmed exoplanets were found to orbit within habitable zones of their related stars : three of the four , Kepler-438b , Kepler-442b and Kepler-452b , are almost Earth-size and likely rocky ; the fourth , Kepler-440b , is a super-Earth . On May 10 , 2016 , NASA verified 1,284 new exoplanets found by Kepler , the single largest finding of planets to date .   Since 1988 , over 3,000 exoplanets have been confirmed by all detection methods , including the Kepler mission ( specifically , planets in planetary systems , including multiple planetary systems , have been confirmed , as of ) .

neg: Ganis Chasma Ganis Chasma is a group of rift zones on the surface of the planet Venus . Bright spots detected by the Venus Monitoring Camera on the European Space Agency 's Venus Express in the area suggest that there may be active volcanism on Venus .

neg: Delta Scuti variable A Delta Scuti variable ( sometimes termed dwarf cepheid ) is a variable star which exhibits variations in its luminosity due to both radial and non-radial pulsations of the star 's surface . The variables are important standard candles and have been used to establish the distance to the Large Magellanic Cloud , globular clusters , open clusters , and the Galactic center . The variables follow a period-luminosity relation in certain passbands like other standard candles such as Cepheids . SX Phoenicis variables are generally considered to be a subclass of Delta Scuti variables that contain old stars , and can be found in globular clusters . SX Phe variables also follow a period-luminosity relation . The recently discovered Rapidly oscillating Ap stars are also a subclass of Delta Scuti variables , found on the main sequence . One last sub-class are the pre-main sequence ( PMS ) Delta Scuti variables .   The OGLE and MACHO surveys have detected nearly 3000 Delta Scuti variables in the Large Magellanic Cloud . Typical brightness fluctuations are from 0.003 to 0.9 magnitudes in V over a period of a few hours , although the amplitude and period of the fluctuations can vary greatly . The stars are usually A0 to F5 type giant or main sequence stars . The high-amplitude Delta Scuti variables are also called AI Velorum stars . They are the second most abundant variable source in the Milky Way after white dwarfs .   Delta Scuti stars exhibit both radial and non-radial luminosity pulsations . Non-radial pulsations are when some parts of the surface move inwards and some outward at the same time . Radial pulsations are a special case , where the star expands and contracts around its equilibrium state by altering the radius to maintain its spherical shape . The variations are due to the swelling and shrinking of the star through the Eddington Valve ( or Kappa ) Mechanism . The stars have a helium rich atmosphere . As helium is heated it becomes more ionised , which is more opaque . So at the dimmest part in the cycle the star has highly ionised opaque helium in its atmosphere blocking part of the light from escaping . The energy from this `` blocked light '' causes the helium to heat up , expand , ionise , become more transparent and therefore allow more light through . As more light is let through the star appears brighter and , with the expansion , the helium begins to cool down . Hence the helium contracts and heats up again and the cyclical process continues . Throughout their lifetime Delta Scuti stars exhibit pulsation when they are situated on the classical Cepheid instability strip . They then move across from the main sequence into the giant branch .   The prototype of these sorts of variable stars is Delta Scuti , which exhibits brightness fluctuations from +4.60 to +4.79 in apparent magnitude with a period of 4.65 hours . Other well known Delta Scuti variables include Altair , Denebola ( β Leonis ) and β Cassiopeiae . Vega ( α Lyrae ) is a suspected Delta Scuti variable , but this remains unconfirmed .

neg: Venera The Venera ( , -LSB- vʲɪˈnʲɛrə -RSB- ) series space probes were developed by the Soviet Union between 1961 and 1984 to gather data from Venus , Venera being the Russian name for Venus . As with some of the Soviet Union 's other planetary probes , the later versions were launched in pairs with a second vehicle being launched soon after the first of the pair .   Ten probes from the Venera series successfully landed on Venus and transmitted data from the surface of Venus , including the two Vega program and Venera-Halley probes . In addition , thirteen Venera probes successfully transmitted data from the atmosphere of Venus .   Among the other results , probes of the series became the first human-made devices to enter the atmosphere of another planet ( Venera 4 on October 18 , 1967 ) , to make a soft landing on another planet ( Venera 7 on December 15 , 1970 ) , to return images from the planetary surface ( Venera 9 on June 8 , 1975 ) , and to perform high-resolution radar mapping studies of Venus ( Venera 15 on June 2 , 1983 ) . The later probes in the Venera series successfully carried out their mission , providing the first direct observations of the surface of Venus . Since the surface conditions on Venus are extreme , the probes only survived on the surface for durations varying between 23 minutes ( initial probes ) up to about two hours ( final probes ) .

neg: Tropospheric ozone Ozone ( O3 ) is a constituent of the troposphere ( it is also an important constituent of some regions of the stratosphere commonly known as the ozone layer ) . The troposphere extends from the Earth 's surface to between 12 and 20 kilometers above sea level and consists of many layers . Ozone is more concentrated above the mixing layer , or ground layer . Ground-level ozone , though less concentrated than ozone aloft , is more of a problem because of its health effects .   Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night . At abnormally high concentrations brought about by human activities ( largely incomplete combustion of fossil fuels , such as gasoline , diesel , etc. ) , it is a pollutant , and a constituent of smog . Many highly energetic reactions produce it , ranging from combustion to photocopying . Often laser printers will have a smell of ozone , which in high concentrations is toxic . Ozone is a powerful oxidizing agent readily reacting with other chemical compounds to make many possibly toxic oxides .   Tropospheric ozone is a greenhouse gas and initiates the chemical removal of methane and other hydrocarbons from the atmosphere . Thus , its concentration affects how long these compounds remain in the air .

neg: Phoebe Regio Phoebe Regio is a regio on the planet Venus . It lies to the southeast of Asteria Regio . It is 2852 km in diameter and is the principal feature of the V41 quadrangle , to which it gave its name . The Venera 13 and Venera 14 landers landed near there .

neg: Stefania (crater) Stephania is a crater on Venus in the northern Sedna Planitia . With a diameter of 11 km it is one of the smaller craters on Venus . Because many small meteoroids disintegrate during their passage through the dense atmosphere , there is an absence of craters smaller than 3 km in diameter , and even craters smaller than 25 km are relatively scarce . The apron of ejected material suggests that the impacting body made contact with the surface from an oblique angle . Upon closer observation it is possible to delineate secondary craters , impact scars from blocks ejected from the primary crater . A feature associated with this and many other Venusian craters is a radar-dark halo . Since dark radar return signifies a smooth surface , it has been hypothesized that an intense shock wave removed or pulverized previously rough surface material or that a blanket of fine material was deposited during or after the impact .

neg: Jupiter trojan The Jupiter trojans , commonly called Trojan asteroids or just Trojans , are a large group of asteroids that share the orbit of the planet Jupiter around the Sun . Relative to Jupiter , each Trojan librates around one of Jupiter 's two stable Lagrangian points , , lying 60 ° ahead of the planet in its orbit , and , 60 ° behind . Jupiter trojans are distributed in two elongated , curved regions around these Lagrangian points with an average semi-major axis of about 5.2 AU .   The first Jupiter trojan discovered , 588 Achilles , was spotted in 1906 by German astronomer Max Wolf . A total of 6,178 Jupiter trojans have been found . By convention they are each named after a mythological figure from the Trojan War , hence the name `` Trojan '' . The total number of Jupiter trojans larger than 1 km in diameter is believed to be about , approximately equal to the number of asteroids larger than 1 km in the asteroid belt . Like main-belt asteroids , Jupiter trojans form families .   Jupiter trojans are dark bodies with reddish , featureless spectra . No firm evidence of the presence of water , or any other specific compound on their surface has been obtained , but it is thought that they are coated in tholins , organic polymers formed by the Sun 's radiation . The Jupiter trojans ' densities ( as measured by studying binaries or rotational lightcurves ) vary from 0.8 to 2.5 g · cm − 3 . Jupiter trojans are thought to have been captured into their orbits during the early stages of the Solar System 's formation or slightly later , during the migration of giant planets .   The term `` trojan '' has come to be used more generally to refer to other small Solar System bodies with similar relationships to larger bodies : for example , there are both Mars trojans and Neptune trojans , and Saturn has trojan moons . NASA has announced the discovery of an Earth trojan . The term `` Trojan asteroid '' is normally understood to specifically mean the Jupiter trojans because the first Trojans were discovered near Jupiter 's orbit and Jupiter currently has by far the most known Trojans .

neg: Helium planet A helium planet is a planet with a helium-dominated atmosphere . This is in contrast to ordinary gas giants such as Jupiter and Saturn , whose atmospheres consist primarily of hydrogen , with helium as a secondary component only . Helium planets might form in a variety of ways . The Gliese 436 b exoplanet is a candidate helium planet .

neg: Carbon tax A carbon tax is a tax levied on the carbon content of fuels . It is a form of carbon pricing . Carbon is present in every hydrocarbon fuel ( coal , petroleum , and natural gas ) and converted to carbon dioxide and other products when combusted . In contrast , non-combustion energy sources -- wind , sunlight , geothermal , hydropower , and nuclear -- do not convert hydrocarbons to . is a heat-trapping `` greenhouse '' gas which represents a negative externality on the climate system ( see scientific opinion on global warming ) . Since GHG emissions caused by the combustion of fossil fuels are closely related to the carbon content of the respective fuels , a tax on these emissions can be levied by taxing the carbon content of fossil fuels at any point in the product cycle of the fuel .   Carbon tax offers social and economic benefits . It is a tax that increases revenue without significantly altering the economy while simultaneously promoting objectives of climate change policy . The objective of a carbon tax is to reduce the harmful and unfavorable levels of carbon dioxide emissions , thereby decelerating climate change and its negative effects on the environment and human health .   Carbon taxes offer a potentially cost-effective means of reducing greenhouse gas emissions . From an economic perspective , carbon taxes are a type of Pigovian tax . They help to address the problem of emitters of greenhouse gases not facing the full social cost of their actions . Carbon taxes can be a regressive tax , in that they may directly or indirectly affect low-income groups disproportionately . The regressive impact of carbon taxes could be addressed by using tax revenues to favour low-income groups .   A number of countries have implemented carbon taxes or energy taxes that are related to carbon content . Most environmentally related taxes with implications for greenhouse gas emissions in OECD countries are levied on energy products and motor vehicles , rather than on emissions directly .   Opposition to increased environmental regulation such as carbon taxes often centers on concerns that firms might relocate and/or people might lose their jobs . It has been argued , however , that carbon taxes are more efficient than direct regulation and may even lead to higher employment ( see footnotes ) . Many large users of carbon resources in electricity generation , such as the United States , Russia , and China , are resisting carbon taxation .

neg: Carbon Carbon ( from carbo `` coal '' ) is a chemical element with symbol C and atomic number 6 . It is nonmetallic and tetravalent -- making four electrons available to form covalent chemical bonds . Three isotopes occur naturally , C and C being stable , while C is a radioactive isotope , decaying with a half-life of about 5,730 years . Carbon is one of the few elements known since antiquity .   Carbon is the 15th most abundant element in the Earth 's crust , and the fourth most abundant element in the universe by mass after hydrogen , helium , and oxygen . Carbon 's abundance , its unique diversity of organic compounds , and its unusual ability to form polymers at the temperatures commonly encountered on Earth enables this element to serve as a common element of all known life . It is the second most abundant element in the human body by mass ( about 18.5 % ) after oxygen .   The atoms of carbon can bond together in different ways , termed allotropes of carbon . The best known are graphite , diamond , and amorphous carbon . The physical properties of carbon vary widely with the allotropic form . For example , graphite is opaque and black while diamond is highly transparent . Graphite is soft enough to form a streak on paper ( hence its name , from the Greek verb '' γράφειν '' which means `` to write '' ) , while diamond is the hardest naturally occurring material known . Graphite is a good electrical conductor while diamond has a low electrical conductivity . Under normal conditions , diamond , carbon nanotubes , and graphene have the highest thermal conductivities of all known materials . All carbon allotropes are solids under normal conditions , with graphite being the most thermodynamically stable form . They are chemically resistant and require high temperature to react even with oxygen .   The most common oxidation state of carbon in inorganic compounds is +4 , while +2 is found in carbon monoxide and transition metal carbonyl complexes . The largest sources of inorganic carbon are limestones , dolomites and carbon dioxide , but significant quantities occur in organic deposits of coal , peat , oil , and methane clathrates . Carbon forms a vast number of compounds , more than any other element , with almost ten million compounds described to date , and yet that number is but a fraction of the number of theoretically possible compounds under standard conditions . For this reason , carbon has often been referred to as the `` king of the elements '' .

pos: Deadpool (film) Deadpool is a 2016 American superhero film directed by Tim Miller and written by Rhett Reese and Paul Wernick , based on the Marvel Comics character of the same name . It is the eighth installment and a spin-off in the X-Men film series , and stars Ryan Reynolds as the titular character , as well as Morena Baccarin , Ed Skrein , T. J. Miller , Gina Carano , Leslie Uggams , Brianna Hildebrand , and Stefan Kapičić . In the film , antihero Deadpool hunts the man who nearly destroyed his life while also trying to reunite with his lost love .   Development began in February 2004 with New Line Cinema , but moved in March 2005 to 20th Century Fox who bought the film rights . In May 2009 , after Reynolds portrayed the character in X-Men Origins : Wolverine , to the general disappointment of fans , Fox lent the film to writers , and Miller was hired for his directorial debut in April 2011 . Enthusiastic acclaim for leaked CGI test footage by Miller in July 2014 led to Fox greenlighting the film in September . Additional casting began in early 2015 , and principal photography commenced in Vancouver from March to May .   Deadpool premiered in Paris on February 8 , 2016 , and was released on February 12 in the United States in IMAX , DLP , D-Box , and premium large format .

neg: Captain Marvel (DC Comics) Captain Marvel , also known as Shazam , is a fictional superhero appearing in American comic books published by DC Comics . Artist C. C. Beck and writer Bill Parker created the character in 1939 . Captain Marvel first appeared in Whiz Comics # 2 ( cover-dated Feb. 1940 ) , published by Fawcett Comics . He is the alter ego of Billy Batson , a boy who , by speaking the magic word `` SHAZAM '' ( acronym of 6 Greek `` immortal elders '' - Solomon , Hercules , Atlas , Zeus , Achilles , and Mercury ) , can transform himself into a costumed adult with the powers of superhuman strength , speed , flight , and other abilities .   Based on book sales , the character was the most popular superhero of the 1940s , outselling even Superman . Fawcett expanded the franchise to include other `` Marvels '' , primarily Marvel Family associates Mary Marvel and Captain Marvel Jr. , who can harness Billy 's powers as well . Captain Marvel was also the first comic book superhero to be adapted into film , in a 1941 Republic Pictures serial titled Adventures of Captain Marvel .   Fawcett ceased publishing Captain Marvel-related comics in 1953 , partly because of a copyright infringement suit from DC Comics , alleging that Captain Marvel was a copy of Superman . In 1972 , DC licensed the Marvel Family characters from Fawcett , and returned them to publication . By 1991 , DC had acquired all rights to the characters . DC has since integrated Captain Marvel and the Marvel Family into their DC Universe and has attempted to revive the property several times , with mixed success . Due to trademark conflicts over another character named `` Captain Marvel '' owned by Marvel Comics since 1967 , DC chose to publish the character 's adventures in a comic book titled Shazam ! for many years , leading many to assume that this was the character 's name . DC later officially renamed the character `` Shazam '' when relaunching its comic book properties in 2011 .   In addition , since 1972 , the character has been featured in two television series adaptations , one live action and one animated , by Filmation , and an upcoming Warner Bros. . Shazam ! feature film scheduled for release in 2019 as part of the DC Extended Universe . Captain Marvel was ranked as the 55th greatest comic book character of all time by Wizard magazine . IGN also ranked Captain Marvel as the 50th greatest comic book hero of all time , stating that the character will always be an enduring reminder of a simpler time . UGO Networks ranked him as one of the top heroes of entertainment , saying , `` At his best , Shazam has always been Superman with a sense of crazy , goofy fun '' .
