The team of advisers who apparent a single lake below the apparent of Mars back in 2018 just appear a new paper acceptance they were wrong. Instead of one lake on Mars, the team thinks there are several.

This makes for what could be the most acute affirmation for exoteric life we’ve seen yet.

According to a paper appear in Nature Astronomy today, the massive 20-kilometer subsurface lake on Mars the group apparent is part of a array of lakes below the apparent of the red planet:

Our after-effects strengthen the claim of the apprehension of a liquid water body at Ultimi Scopuli and announce the attendance of other wet areas nearby. We advance that the waters are hypersaline perchlorate brines, known to form at Martian polar regions and anticipation to survive for an continued period of time on a geological scale at below-eutectic temperatures.

Using data generated from the European Space Agency’s Mars Express orbiter, the team initially apparent the first body of water by analytical ‘bright spots’ that showed up on appropriate RADAR images.

The big idea here is that, much like Earth’s many subsurface bodies of water, Martian underground lakes are likely caused by acute burden from apparent glaciers. In the past, such ideas have been absolved due to the fact that Mars is much colder than our planet. But the astronomers who apparent the Martian subsurface water bodies accept they’re able to remain in liquid form due to being acutely salty, thus giving them a much lower freezing point.

The news that there could be several bodies of water below the red planet’s apparent is exciting, but we should take these briny lakes with a grain of salt.

Firstly, we’re not sure there absolutely are subsurface lakes on Mars. It’s accessible there’s addition account for the “bright spots,” although it bears acknowledgment that the team corroborated the data using assorted indicators this time around so it’s as legit as it can get after sending a team of robots with shovels.

And therein lies the rub. As far as we know, humans don’t have the kind of space-faring conduct accessories all-important to get to the accurate bottom of Mars‘ lake bearings so we’ll be stuck allegory data for at least a few more years.

This, of course, also doesn’t mean there are little green people living in underground caves on Mars. But it very well could mean that Mars is abundant with life. There are plenty of simple life forms that could survive in such an environment.

In fact, it appears as though the Martian salt lakes would make a acceptable abode for at least one animal we know of: the lovable, airy tardigrade.

Theoretically speaking, water bears could survive on Mars‘ apparent for at least a little while due to their adeptness to enter a hibernation-like state called cryptobiosis. But eventually a water bear dies if it charcoal in an brusque environment.

But subsurface salt lakes could accommodate a safe haven for tardigrades and other lifeforms by careful them from the harshest ecology apparent factors. The attendance of liquid water indicates that assertive kinds of single-celled bacilli and algae could survive, thus accouterment a accessible food source for more avant-garde creatures like water bears.
