So I was browsing a bit, and I ran across This.

Direct photo of extrasolar planets. Just... damn. Planets. I mean yes, they're gas giants larger than Jupiter at orbits that start at Saturn and go farther out, but how many years ago we were looking at stellar wobble and using that to guestimate even IF there were extrasolar planets...

We've been able to see dust disks, including lumps in the disks. for quite a while now. But THAT is cool that we can clearly see the planets. That's exciting because it isn't speculation. It will be interesting to see if they can confirm the "calculated" planets around those hundreds of stars they've used other methods to determine the existence of planets. And now we can do spectrographic analysis on them to see what elements they are made of! Very exciting!

But about those disks... I even used some of the pics in some of my old starfire-related stuff.

One of my favorites is of Fomalhaut:

And here you can see they identified what they believe is a planet at Fomalhaut:

Hubble image as far back as 1997:

Wow, I'd have been happy if they could have just seen Planets, but to actual see PLANTS, they must be enormously huge, 10 to 100 times the size of redwoods, eh? ;)

I'm just giving ya a little ribbing Cralis, because I just found out that someone put his/her wooden shoe into my APoD empire's shipyard machinery (not quite a high-tech loom, but the analogy should work.). And that has "Clogged" up my building schedule a bit.

Yet more reasons to want an orbital interferometer - it would allow much easier imaging of distant systems.
