Water on Mars!! Do life exist there??

A Huge lake of salty water appears to be buried deep on Mars, raising the possibility that more water and maybe even life exist there, international astronomers have said.
It is the largest body of liquid water ever found on the Red planet. Water is essential to life as we know it, scientist have long sought to prove that the liquid is present on Mars.
This lake water, however, is not drinkable, and lies 1.5 km beneath the icy surface in harsh environment.
The lake is so cool and briny, and mixed with the heavy dose of Martian salt and Minerals. Its temperatures likely below freezing point of water, but it can remain liquid due to the presence of magnesium, calcium and sodium.
"If this researchers are right", then this is the first time we have found evidence of a large water body on Mars, "said , a geophysicist at the University of Texas who found signs of an enormous Martian ice deposit in 2016.
It has at least took two years to examine the data to make sure they had detected water not ice on other substance.
In May, Nasa launched another spacecraft, the insight Mars Lander, that will dig under the surface after it reaches a flat plain just north of the Martian equator in November.
