根据文章第二段Earth is the only known planet that stays in a perfect position from our Sun to support water in a liquid state.Astronomers call this perfect distance from a star the "habitable (宜居的)" or "Goldilocks zone".(地球是已知的唯一一颗距离太阳很近的行星,...
U.S. space agency NASA announced on Monday it has found "strong" evidence that there is liquid water intermittently flowing on present-day Mars. Images taken from the Mars orbit showed dark, finger-like markings that, typically less than five meters in width, appear on slopes during warm sea...
TPO-8-3：Running Water on Mars Photographic evidence suggests that liquid water once existed in great quantity on the surface of Mars. Two types of flow features are seen: runoff channels and outflow channels. Runoff channels are found in the southern highlands.These flow features are ...

surface liquid water may be found on the night side which is also protected from the energetic radiation of the host star in its early evolutionary stages. On further out planets, which may be less vulnerable to radiation but too cold for surface liquid water, basal melting may produce long ...
Another solution, mm, which was proposed much later, was that perhaps the young Sun wasn't faint at all. Perhaps it was bright.So it's called the "bright young Sun" solution, according to which the Sun would have provided enough heat for the water on Earth and Mars to be liquid. ....
