Aliens?? [NASA Discovery Announcement]

I wouldn't get my hopes too high. It might be a simple spore or bacteria, if that. It will be interesting to find out though, and where it resides. Thanks for the heads up.

Seriously? If it was so much as an extraterrestrial bacterium, it would be earth-shattering. Discovery of any kind of life on another planet would be absolutely amazing.

But it's most likely something chemical or atmospheric somewhere else. Something like "we've found a planet/moon/large asteroid where ____ exists, which means it could support life."

If it was truly life, I think it'd be more tightly-wrapped. "A press conference on Wednesday" is a little anti-climactic for that kind of discovery. IMO.
