” or RSL, which are dark linear features found on steep slopes in specific regions of Mars. RSL display seasonal changes, appearing in warmer seasons and fading in colder seasons, in a way that is consistent with the behavior of liquid water. Distinct striped and polygonal features in Martian...

In doing so, they were able to compare data obtained from MARSIS of the area surrounding the body of water found on Mars, which allowed them to confirm that it was in fact liquid. The method also allowed researchers to locate a number of other wet patches around the la...
The April study noted the presence of perchlorates -- a kind of salt -- which could make the boiling point of Mars's water much higher, theoretically allowing it to remain liquid. They posited(假定,推测) that the planet's temperature would be right for liquid, perchlorate-filled water to...
Scientists have found the first evidence that briny water flowed on the surface of Mars during the planet’s summer months. The confirmation of water on the surface of Mars is important and would raise a host of questions, chief among them: Where is the water coming from, and what does ...
It has a surface temperature neither too hot nor too cold for liquid(液态)water. Scientists think there is a chance that the planet could have life. The planet Gliese 581g goes around a star called Gliese 581 which is about 20 light-years from Earth. That is about 194 trillion(万亿)...
Liu Yang, a scientist at the State Key Laboratory of Space Weather of the National Space Science Center and lead author of the paper, said their findings indicate that liquid water activities might have been more active than previously thought during the Amazonian epoch, which began about 3 ...
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 ...
Liquid water may still flow on Mars, but that doesn't mean it's easy to spot. The search for water on the Red Planet has taken more than 15 years to turn up definitive signs that liquid flows on the surface today. In the past, however, rivers and oceans may have covered the land....
Liquid water is an important prerequisite for life to develop on a planet. As researchers report in a new study, liquid water could also exist for billions of years on planets that are very different from Earth. This calls our currently Earth-centered idea of potentially ...
