The latest computer models are telling scientists that more than a third of the star systems containing jupiterlikegas giants may also harbor earthlike planets 最新的计算机模型显示,包含有类似木星这样的巨形气态行星的星系有1 / 3可能孕育出类地行星
" we will be able to isolate the light of these planets and tell whether or not the planets we are looking at are giant planets or earth - like planets , ” said mr 我们将有能力将这些星球的光谱分离出来,并辨别我们所观测的行星是巨型行星还是类地行星。
Although we may never be able to verify this hypothesis on earth , we may be able to test it indirectly by observing earth - like planets orbiting other stars 纵使这个假说可能永远无法在地球上获得验证,但藉由观测环绕其他恒星运行的类地行星,或许能间接验证。
Plagioclase widely spreads across the earth surface , and causes relevant geological movements such as landslide and debris flow , which become one of most broad and severe geological catastrophes 本文采用比较行星学的方法,认为陨击作为太阳系普遍的地质过程,地球跟太阳系其他类地行星受到陨击的情况是相类似的。
If such planets exist , these missions ? nasa ' s terrestrial planet finder and esa ' s darwin ? should be able to scan their atmospheres for the presence of gases that would indicate the existence of life 如果真的有这类行星存在, nasa的类地行星搜寻者,以及esa的达尔文计画等任务,将得以探测它们的大气,寻找象徵生命存在的气体。
