Scientists, while studying the surface of Mars, discovered lakes containing salt water there. The results of the study were shared by specialists from Italy, as reported on the pages of Nature Astronomy.

In the course of the work, its authors analyzed the data collected by the Mars Express station launched by the ESA. According to astrophysicists, the lake can cover 20 to 30 km across, with a depth of about 1.5 km under the ice-covered surface of the South Pole of Mars. Three small ponds were found around the reservoir, but they do not connect with the main lake.
The researchers point out that in the presence of water, the likelihood of microbial life on the Red Planet and under its surface increases significantly. High salt content can prevent the liquid from freezing. Scientists assume that even 4 billion years ago, Mars was a warm and humid planet, which eventually became a desert world against the background of the disappearance of the magnetic field.
