They found a lakebed on Mars that, in its heyday, probably had all kinds of life swirling in it... alligators, turtles, bass fish, cute little alien minnows (aww)!
But, in all seriousness - this means Mars used to have a freshwater lake, which might have been home to Martian life.
I should be more excited.
See, the thing is, water on Mars isn't anything new to this site, or any avid astronomer, ufologist, space nut, spaced out nut for that matter. Case in point:
Why the constant stream of second-rate stories?
Why do we keep pretending like this is new information? Why do we keep pretending like we haven't thought the implications through? Why do we keep pretending like we haven't all watched Ancient Aliens?
Despite the flood of evidence that water - oceans even! - once existed on Mars, some of us remain stubborn to the end:
