The recent discovery of numerous extrasolar planets confirms that our solar system is not unique 從最近發(fā)現(xiàn)的大量太陽(yáng)系以外的行星,可以確定我們的太陽(yáng)系并非獨(dú)一無(wú)二的。
So say three teams of scientists who used the spitzer space telescope to capture the light spectrum of two known extrasolar planets 三支科學(xué)家小組用“斯必?fù)瘛笨臻g望遠(yuǎn)鏡捕獲了兩個(gè)已知的太陽(yáng)系外行星的光譜。

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 現(xiàn)在天文學(xué)家已經(jīng)在太陽(yáng)系之外發(fā)現(xiàn)了50多顆行星,他們只有發(fā)現(xiàn)一些真正奇怪的東西才能吸引人們的注意力。
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 為實(shí)現(xiàn)這一目標(biāo),科學(xué)家將望遠(yuǎn)鏡鎖定在14顆太陽(yáng)系外行星中的兩顆上,這些行星是已知的從地球可以看到其直接從它們的主星前面經(jīng)過(guò)的系外行星。
An extrasolar planet, or exoplanet, is a planet outside the Solar System. A total of such planets (in planetary systems, including multiple planetary systems) have been identified as of .
