The folks at the Hawaiian Volcano Observatory take some pretty amazing pictures. The most recent one shows incandescent smoke plume at Kilauea's summit crater just before dawn. It looks really alien and spacey, with the stars in the background. It's a bit big so it's under a cut.
While talking about cool pictures, a picture of mine taken pretty close to my office got short-listed to be included in the California Guide of some website called Schmap. No clue what the heck they are, but I'm kind of flattered that somebody like that picture. I remember that I did try to make it quasi-artistic, or at least with good composition and balance. Whatever. Here it is.
