My son, the spot

A few weeks ago I wrote about a new storm on Jupiter named Oval BA. Although it’s not really named after me or my website, it’s still pretty cool. Hubble released the image above of the new storm just today. Go to that link (or some of the others on the HST site) and take a look at the images for context. To give you some idea of the size of this monster, you could dunk the whole Earth into it. Jupiter is amazing; it can operate on some truly incredible scales.

Incidentally, Jupiter is now rising earlier every night, and by 10:00 p.m. it has cleared my neighbor’s trees. The other night I pulled out my ‘scope (with my friend Fraser Cain, who runs Universe Today) and just missed Io, one of the bright moons, going across the face of Jupiter! I’ve watched that happen before, and it’s very cool to track it happening (it takes about 3 hours for Io to cross Jupiter). You can see the moons easily with just binoculars (a tripod helps), so now is the time to start watching the King of the Planets.’
