When I read that an impact had been spotted on Jupiter, I figured it was somewhere other than the equator, which would be a bulls-eye. Even Shoemaker-Levy, a huge comet broken into a string of pieces, slammed like a series of machine gun bullets into Jupiter near its south pole.

But this one was bigger. See above. And read the story. That black hole in the side of Jupiter is nearly as big as our whole planet. [Woops, not quite. DFR points out in a comment below that the black spot is certainly a moon shadow. Jupiter has four big ones, they do make shadows like that, they are all on the planet’s equator, they’re all a good deal smaller than the Earth (being moons), and I should have known better. Anyway…

And nobody saw it coming.

One good thing is that Jupiter is kind of a crap sweeper, gliding around the inside edge of the outer solar system with a nice big gravitational field, sucking up debris that might otherwise clobber one of your inner planets, such as ours.

By the way, that bright point of light in the eastern sky these evenings is Jupiter. The smaller points of light on either side of it and close by are its moons. The clear-eyed can make them out on a dark night. And they’re quite obvious through good telescopes.

Oh, by the way, there’s a total solar eclipse happening right now in Asia. The NASA server with cool info seems to be hosed. So do some other sites I’ve checked (not that my connection is good right now… we’re back to high latencies again). But Shadow & Substance is on the scene and covering it live. Lots of fun stuff there.
