NASA, even the modern, financially eviscerated version of NASA, continues to make mind boggling discoveries, one after another after another. In today’s discovery, there is water on Mercury! Well, ice, which surprised me just as much.
See, I always figured that Mercury, being the closest planet to the sun, would also be the hottest, the kind of place where if you got too close to it you would suddenly burst into flames like an overextended marshmallow and melt into nothingness before you could say shvetz, which is actually much quicker than saying “Jack Robinson” or even “Bob’s your uncle,” so score one for the Czechs there.
Truth is, that’s Venus I’m thinking about because Venus actually has an atmosphere, not a very nice one but, nonetheless, it’s an atmosphere and that traps the heat so Venus is permanently hotter than an actual fire on earth. Mercury, having pretty close to no atmosphere at all, gets really hot on the side that’s facing the sun when it’s facing the sun (i.e. daytime) and then super cold at night.
At the poles, though, because Mars doesn’t tilt hardly at all (Earth does, which explains the seasons), the sun is virtually never seen, so it’s been super cold like forever. There, there is ice. It’s not as if we’re going to send up colonists any time soon, we’ve barely got a toehold on Antarctica and this is a whole hell of a lot colder and there are no cute penguins, but it’s still a pretty amazing discovery. You could chalk up my not knowing about the lack of atmosphere and tiltillation just to my ignorance of local affairs, but the ice is a totally new thing.
Speaking of Antarctica, I flipped over to this article after reading about Mercury and from the headline I was hoping they’d have discovered some extraterrestrial life form (perhaps “hope” is the wrong word, in view of every science fiction monster movie ever), but no, it was more just about the drilling through the ice and the fact that this lake was sealed off for thousands of years and they still found microbial life so it proves that life can sustain itself damned near anywhere there is water.
Why not Mercury?
