Scientists Found Lakes Of Liquid Water On Mars

Scientists found brightest spots on Mars which was made using data from a radar instrument on the European Space Agency's (ESA) Mars Express spacecraft, which has been orbiting the Red Planet since December 2003.

Scientist said that the spots are lakes. The finding is based on 29 observations which are collected by Marsis radar between 2012 and 2015.

After that, in 2018, scientists observed a 20km-wide subsurface lake located 1.5km under Mars' south polar layered deposits.

And between 2010 and 2019, scientists have analysed a dataset of 134 radar profiles.

Scientists said, the main lake is surrounded by smaller bodies of liquid water but there's not enough heat at these depths to melt the ice, so scientists believe the liquid water must contain high concentrations of dissolved salts and these salts can lower the water's freezing points.

There is ongoing research into whether life could survive in conditions like those in the lakes on Mars because salt in very high concentrations is not very friendly to life.
