Life on Mars may have lived below surface for this shocking reason - Fox News

The research, published in Science Advances, suggests that ice sheets below the surface melted because of geothermal heat, generating water, providing the perfect environment for any form of life.

“I and my co-authors propose that the faint young sun paradox may be reconciled, at least partly, if Mars had high geothermal heat in its past.”.

A separate group of researchers suggested in January 2020 that the water on Mars once contained the right ingredients to support life.

Last month, another group of researchers suggested there was water on Mars' surface 4.4 billion years ago, before life existed on Earth.

Ojha and the other researchers looked at various datasets to see if geothermal heat would have been present, or possibly, during the Noachian era (4.1 billion to 3.7 billion years ago) and determined there was, well below the surface.

NASA's InSight lander, which landed on Mars in November 2018, could aid experts in understanding geothermal heat and if it played a role in life on Mars, the researchers said in the statement. 

In October, a separate group of researchers found that Mars has an abundance of liquid water in the underground lakes in its south pole
