(被视作和谐体系的)宇宙Among the factors that stand out in the Orphic construal of a cosmos is the nature of time。10 interstellar a. 星际的It is possible that we have traces of interstellar dust in meteorites。11 galaxy n. 星系It starts at zero and eventually the galaxies are moving apart at a steady speed。12 intergalactic a. 银河间的， 星系间的Alternatively the capsule might be drifting in the weak gravitational field of intergalactic space。13 The Milky Way n. 银河系One reason to think that the Milky Way had such a meal several billion years ago is its structure。14 The Big Bang n. 宇宙大爆炸The Big Bang theory is the belief that the universe originated as the result of a large explosion of a single mass of matter。15 comet n. 彗星Astronomers had accidentally caught a comet in the act of turning into an asteroid。16 asteroid n. 小行星Extraction of helium-3 from the surfaces of asteroids is not likely to compare with that from the Moon。17 satellite n. 卫星， 人造卫星One month later a second satellite was launched into a somewhat higher orbit, of between 234 and 244 miles。18 meteor n. 流星From time to time Earth suffers bombardment from meteors and comets, and meteoritic impact has been a major planet-shaper and climate-modeler。19 meteorite n. 陨石Some people believe that dinosaurs were destroyed because of the effects of a gigantic meteorite。20 revolution n. 旋转， 转数The planet rotates in the same direction as its revolution around the sun。21 rotation n. 旋转， 转动It takes 243 Earth days for Venus to complete one rotation。22 radiation n. 放射， 发光， 辐射Sensors detected a dangerous level of radiation。23 constellation n. 星座， 星群Scientists have discovered a new a star in the constellation of Orion。24 cluster n. 串， 束， 群 v. 使成群， 聚集Most galaxies are found in clusters rather than in isolation。25 lunar a. 月球的， 有关月球的The first lunar module is now on display at the Smithsonian Air and Space museum in Washington。26 eclipse n. (日，月)蚀No solar eclipses will be visible from the United States in 1996, and only two will be visible from Earth。27 velocity n. 速度， 迅速， 速率In addition, there is no difference in velocity between movements which are long and those which are short。28 corona n. 日冕， 冠状物Corona is a circle of coloured light that can sometimes be seen around the moon at night。29 terrestrial a. 地球的， 陆地的， 地球上的A statistical analysis based on this data suggests that well over half the stars are being orbited by rocky terrestrial material。30 planetary a. 行星的The book lists all predictable astronomical phenomena for the coming year, such as planetary, lunar, and eclipse data。31 exploration n. 考察， 勘探， 探查Further exploration and appraisal drilling will be necessary to confirm the commercial potential for this discovery。32 hypothesis n. 假说， 假设， 前提， 猜测Our hypothesis is that the dolphins ate contaminated fish, and this affected the dolphins immune system。33 assume v. 假定， 假设We cannot assume the suspects to be guilty simply because they have decided to remain silent。34 collision n. 碰撞， 冲突These airbags are designed to protect car drivers in head-on collisions。35 supernova n. 超新星Another theory suggests that a supernova explosion occurred, destroying the companion sun and scattering its material toward our Sun。36 nova n. 新星Apparently a nova is a close binary system, made up of a cool, normal star and a White Dwarf。37 light year n. 光年The Japanese company is light years ahead of its European competitors。38 gravitation n. 万有引力Newton worried about that when his theory of g
