A rocky planet takes a hit from a comet in an artist's impression of what could be going on around the nearby star Eta Corvi.
一颗岩石行星遭到了彗星的撞击，在一位艺术家的印象里，这可能就是在乌鸦座eta星附近发生的情况。
But Eta Corvi is significantly brighter than the sun, so its habitable zone, where life-sustaining liquid water can exist, is correspondingly farther out.
然而EtaCorvi是一颗比太阳明亮得多的恒星。因此它的可生存区域(即支持生命存在的液态水可以存在的区域)相应地要大得多。
