太阳系外行星系 |
| 2. | The recent discovery of numerous extrasolar planets confirms that our solar system is not unique
从最近发现的大量太阳系以外的行星，可以确定我们的太阳系并非独一无二的。 |
| 3. | So say three teams of scientists who used the spitzer space telescope to capture the light spectrum of two known extrasolar planets
三支科学家小组用“斯必择”空间望远镜捕获了两个已知的太阳系外行星的光谱。 |
| 4. | Gives overview of the solar system , the milky way galaxy , extrasolar planets , cosmology and astrophotography . includes images , additional resources , and forums
-站点设立于广西柳州，内容包含天文知识，图片欣赏，宇宙生物探讨课题，同时包含论坛交流服务。 |
| 5. | With some 50 extrasolar planets under their belt astronomers have to announce something really strange to get anyone ' s attention . last week they did just that
现在天文学家已经在太阳系之外发现了50多颗行星，他们只有发现一些真正奇怪的东西才能吸引人们的注意力。 |
| 6. | Studying these giant planets and their weird satellites helps us understand not only the formation of the solar system but also the planetary systems of extrasolar worlds
研究这些巨行星和它们千奇百怪的卫星，将有助我们了解太阳系的形成过程，以至太阳系外其他的行星系统。 |
| 7. | To accomplish this , scientists focused the telescope on two of the 14 extrasolar planets that are known to pass directly in front of their star when observed from earth
为实现这一目标，科学家将望远镜锁定在14颗太阳系外行星中的两颗上，这些行星是已知的从地球可以看到其直接从它们的主星前面经过的系外行星。 |
| 8. | Three other extrasolar planets believed to be of rocky composition have been reported , but they orbit a pulsar - the flashing corpse of an exploded star - rather than a normal type of star
之前人们曾报道过另外三颗据信由岩石组成的太阳系外行星，但是，它们是围绕着一颗脉冲星（恒星爆发后遗留的发光的残存物）运转的，而不是一颗常态的恒星。 |
| 9. | But starting with the 1995 discovery of the first extrasolar planet a gassy monster like jupiter but orbiting seven times as close to its star as mercury orbits around our sun each new find has seemed stranger than the last
但1995年发现了第一颗太阳系之外的行星一颗像木星一样的巨大气态星球，它围绕自己的母星运行的距离比水星绕着太阳运行时的距离还近7倍。 |
| 10. | For example , if there is a planet orbiting around the neutron star , it will wobble a little and the pulses will come a little early or late . we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses . this is how the first extrasolar planet is discovered
例如假若有一颗行星围绕一颗中子星运行，它会令中子星出现摇动，引致脉冲的间隔变长或短，由此我们根据脉冲周期的变化，可推断出行星的质量和轨道半径，这亦是天文学家找出第一颗地外行星时所用的方法。 |
