If you can cast your mind back through the mists of time to last week, you may remember we reported on a very sad (for the alien enthusiasts among us) new study that revealed our strongest evidence for liquid water on Mars was nothing more than a dusty mirage, shattering our most potent hope for discovering microbial life on the red planet.
Now, however, the researchers who provided the original evidence back in 2018 have come back with a vengeance, doubling down on their conclusions that there actually IS a sub-glacial liquid lake on Mars in a new study.
So, what’s the deal? IS there liquid water on Mars or not?
