Added 1 new A* page:Well it's official: A* artwork, mostly framed original art, will be showing at Couth Buzzard at 83rd and Greenwood in Seattle from this Friday through the end of October. It's a combo used bookstore / espresso joint! This is something of a surprise show—my dad just found out they had a spot for me yesterday—so I won't have any originals there that you wouldn't have seen if you came to my show earlier in the summer, but if you *didn't* make it to that one, well now you've got a couple months to catch them at the Buzzard.

A couple science things happened!
- Explosion on Jupiter - An amateur astronomer spotted a several-second-long flash on Jupiter, which he guesses was an impact, possibly from a small, unknown comet. This is the fourth impact observed on Jupiter since 2009; they haven't been nearly as spectacular as the massive Shoemaker-Levy comet impact of 1994, which hit Jupiter with an energy equivalent to the output of about 11 million thermonuclear warheads—I calculated that for an A* thing a few years ago—leaving huge black spots on top cloud layers of the gas giant.
- A new theory points out that the geologic formations seen on Mars that have long been thought to show traces of erosion by ancient waterways or seas could actually have been formed by cooling magma rather than water—there's a region of French Polynesia with clays similar in composition to Martian ones, and these Polynesian ones were shown four years ago to have been formed by rapidly cooling magma, rather than by slow erosion by water. Still, scientists are pretty confident that water has played a role in the geology and chemistry of Mars, so this apparently doesn't shoot down the possibility of past Martian water-dependent life, which people are always hopeful of finding for some reason.
