We have been scouting out new planets for a few years now. First we started measuring a sun's 'wobble' to infer the mass and distance of it's planet(s). Before now we've never actually gotten a clear, direct image of an extra-solar planet.

I imagine that we'll (the we that is the Earthly Scientific Community) make more complex and exciting discoveries more frequently.

The BBC has a nice cache of these discoveries.

Imaged extra-solar planet

@jespah,

That would be cool! But, I don't think I could speculate on the likelihood.

The universe is probably teaming with life.

Most likely we will not see any of it in our lifetimes.

If it shows up here:
that 's not a good thing.
Remember what happened to the Indians
after Columbus arrived.

@OmSigDAVID,

Good point. And what happened here when the hypothetical comet arrived bringing seeds of life - if that's how it all began, it changed everything for ever.

@littlek,

Well, I'm thinking of alien bacteria or the like. I think finding that -- a cell on another world -- I think that would change our world. And I don't mean in an Andromeda Strain kind of way, more that it would really inspire people,, to know that we're not alone out there. I don't expect little green men, but a microscopic something on Europa or some place like that? That would be astounding.

littlek: really cool picture. thanks for posting. Smile

jespah: finding extraterrestrial life would sound the death knell for biblical literalism i think, which would be a good thing as far as i'm concerned.

New planets around a star called 24 Sextanis are called Sex A, Sex B, and Sex C. Yes, Sex C. Apparently it is too Sex C for our solar system. Of course they were named in California.
