Wednesday December 27 2006 Guardian Unlimited 1 A European spacecraft took off today to spearhead the search for another Earth among the stars 2 The Corot space telescope blasted off aboard a Russian Soyuz rocket from the Baikonur cosmodrome in Kazakhstan shortly after 2 20pm 3 Corot short for convection rotation and planetary transits is the first instrument capable of finding small rocky planets beyond the solar system Any such planet situated in the right orbit stands a good chance of having liquid water on its surface and quite possibly life although a leading scientist involved in the project said it was unlikely to find any little green men 4 Developed by the French space agency CNES and partnered by the European Space Agency ESA Austria Belgium Germany Brazil and Spain Corot will monitor around 120 000 stars with its 27cm telescope from a polar orbit 514 miles above the Earth Over two and a half years it will focus on five to six different areas of the sky measuring the brightness of about 10 000 stars every 512 seconds 5 At the present moment we are hoping to find out more about the nature of planets around stars which are potential habitats We are looking at habitable planets not inhabited planets We are not going to find any little green men Professor Ian Roxburgh an ESA scientist who has been involved with Corot since its inception told the BBC Radio 4 Today programme 6 Prof Roxburgh said it was hoped Corot would find rocky planets that could develop an atmosphere and if they are the right distance from their parent star they could have water 7 To search for planets the telescope will look for the dimming of starlight caused when an object passes in front of a star known as a transit Although it will take more sophisticated space telescopes planned in the next 10 years to confirm the presence of an Earth like planet with oxygen and liquid water Corot will let scientists know where to point their lenses 8 Measurements of minute changes in brightness will enable scientists to detect giant Jupiter like gas planets as well as small rocky ones It is the rocky planets that could be no bigger than about twice the size of the Earth which will cause the most excitement Scientists expect to find between 10 and 40 of these smaller planets 9 Corot will also probe into stellar interiors by studying the acoustic waves that ripple across the surface of stars a technique called asteroseismology 10 The nature of the ripples allows astronomers to calculate a star s precise mass age and chemical composition 11 A planet passing in front of a star can be detected by the fall in light from that star Small oscillations of the star also produce changes in the light emitted which reveal what the star is made of and how they are structured internally This data will provide a major boost to our understanding of how stars form and evolve Prof Roxburgh said 12 Since the discovery in 1995 of the first exoplanet a planet orbiting a star other than the Sun more than 200 others have been found by ground based observatories 13 Until now the usual method of finding exoplanets has been to detect the wobble their gravity imparts on parent stars But only giant gaseous planets bigger than Jupiter can be found this way and they are unlikely to harbour life 14 In the 2010s ESA plans to launch Darwin a fleet of four or five interlinked space telescopes that will not only spot small rocky planets but analyse their atmospheres for signs of biological activity 15 At around the same time the US space agency Nasa will launch Terrestrial Planet Finder another space telescope designed to locate Earth like planets 615 words Questions Choose the appropriate letter from A D for question 1 1 Corot is an instrument which A can help to search for certain planets B is used to find planets in the orbit C can locate planets with human beings D can spot any planets with water Do the following statements agree with the information given in the reading passage For questions 2 5 write TRUE if the statement agrees with the information FALSE if the statement contraicts the information NOT GIVEN if there is no information on this in the passage 2 Scientists are trying to find out about the planets that can be inhabited 3 BBC Radio 4 recently focuses on the broadcasting of Corot 4 Passing objects might cause a fall in light 5 Corot can tell whether there is another Earth like planet Based on your reading of the passage complete the sentences below with words taken from the passage Use NO MORE THAN THREE WORDS for each answer With measurements scientists will be able to search for some gaseous and rocky planets They will be extremely excited if they can discover some small 6 the expected number of which could be up to 7 Corot will enable scientists to study the 8 of stars In this way a star s mass age and chemical composition can be calculated According to Prof Roxburgh changes in light can be caused by passing planets or star 9 The related statistics can gain us a better 10 of the star formation and evolvement Observatories have found many exoplanets which are 11 other stars than the Sun The common way used in finding exoplanets can only detect huge gas planets which do not 12 With the launching of Darwin astronomers will be able to analyse whether those rocky planets have 13 for life Answer keys 1 答案 A
