In 2018, planetary scientist Roberto Orosei and his colleagues stirred up a multi-planetary controversy when they claimed they’d found evidence of a subglacial lake nearly a mile below ice at Mars’s south pole. At the time, fellow planetary scientists met the claims with intense scrutiny.
Now, Orosei, a planetary scientist at Italy’s National Institute for Astrophysics, and his fellow researchers say they have new, additional evidence that these deep, vast subglacial lakes really do exist. They published their findings this week in the journal Nature Astronomy.

If these lakes are, in fact, real, they could reshape our understanding of whether life could still exist on Mars. “This area is the closest thing to ‘habitable’ on Mars that has been found so far,” Orosei told Science News.
