Circumstellar Disks. (Thank you, gb!)
I found this excellent site regarding Beta Pictoris and company:
Circumstellar Disk Library
I'm not at all demeaning Keck's results on this, (I thought of Carl Sagan when I saw the photos?!!), but I also hope that they will point this <a href="http://sirtf.caltech.edu/fellow's eyes on those disks as well. The exoplanet group should get plenty of scope time.
