"While we agree that the occurrence of another truly Earth-like planet is trivially impossible, we hold that this argument does not constrain the emergence of other inhabited planets," Heller and Armstrong write. In other words, keep your "Star Trek" dreams alive and always remember thePrime D...
We find that there was a maximum number of habitable planets around the time of Earth's origin. If at all, interstellar panspermia was most probable at that time and may have kick-started life on our planet. 展开 关键词: Panspermia habitable zone Earth-like planets planet formation star ...

There is, remarkably, even a catalogue of “super-habitable planets” which were proposed and defined by Heller and Armstrong in 2014. (Heller & Armstrong, 2013) These worlds would be, potentially, even more amenable to the emergence, evolution, and persistence of life than Earth itself is. ...

Superhabitable planets: Alien worlds that may be more habitable than Earth The researchers suggested three criteria that might be important in determining a galaxy's habitability. The first was the total mass of their stars, representing potential homes to planets. The next was the amount of mas...
根据文章第一段Scientists have found a potentially habitable (可居住的) planet and its star outside our Solar System are more similar to the Earth and our Sun than any other known planet-star pair.可知,科学家发现,一个潜在可居住的行星及其在我们太阳系之外的恒星比其他任何已知的行星恒星都更类似...
根据第四段的首句“But Kepler’s primary goal was always to determine how common planets like Earth are.”可知,Kepler的首要任务是确定像地球一样的星球是多常见。故选A。【4】主旨大意题。根据第五段中“It took more than half a century for scientists to start pinning down how many planets could...
