A large underground saltwater lake is discovered on Mars, according to a new study. Scientists believe that it increases the chances of finding life on the red planet.
A 20-kilometer-wide water reservoir sits under a layer of ice 1.5 kilometers thick, according to Italian researchers from the National Institute of Astrophysics of Bologna. The study was published in the American journal Science Wednesday
Researchers analyzed the radar signals collected from the south pole of Mars by the ESA Mars Express spacecraft.

Water is a prerequisite for life that scientists have been searching for for a long time on Mars.
John Bridges, scientist of the planet, at the University of Leicester believes that his Italian colleagues have found clear evidence that there is water on the planet.
– They conducted a thorough analysis. According to The Guardian, [traduction]
Toxic and Cold
In this case, however, researchers can not determine whether the discovery is a sea or a layer of sludge. In addition, the amounts of water have high proportions of salt perchlorates. Perch chlorates are very toxic and are likely to float water at very low temperatures.
– This guarantees uncomfortable conditions for life. I think this is really at the edge of the circumstances in which life may exist, "said Roberto Orosei, one of the researchers behind the report.
The finding is supported by Professor Kirsten Siebach at the 39 Rice University.
– If there is water It is very cold, says Siebach, at the point of freezing
The trace of the rivers is the most obvious sign of life on March It is estimated that there are 3.6 billion years ago, the red planet had large amounts of floating water and lakes, according to researchers.March is now cold Desert and dry
