Very interesting observation of a dark mark on Jupiter... it's starting to ripple out across Twitter...

Very cool. Given how much Jupiter eats comets and asteroids, wouldn't be all that surprising. Now if only this would happen on Saturn
Otherwise, the monolith seems to be a year early -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

I started my own topic, but then nprev pointed out that Stu beat me to it here, so I'm reposting...
It looks pretty convincing to me. Apparently it wasn't there a couple of days ago. The clincher will be methane-band images which will reveal whether the dark spot is at low altitude (and thus meteorological) or at high altitude (and thus probably impact-generated). The NASA Infrared Telescope on Mauna Kea is planning to check it out tonight, and I'm sure there will be lots more amateur images soon. nprev asked how soon Hubble could be reprogrammed to look at this, if it was considered worthwhile. It's normally a couple of weeks at the shortest, but with the post-repair recommisioning still in progress, it might be harder to respond so quickly at the moment. John. |

Yeah, I was afraid of that, but had to ask. If it is an impact (scar? tear? hole? astrobleme? What do we call atmospheric impact artifacts on the gas giants, anyhow???) it probably won't persist for more than a few weeks regardless. Guess it's up to the big Earthside observatories to carry this one. Clear skies & good luck, you guys! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

They have already done one science observation (a KBO mutual event with STIS that couldn't be rescheduled), so it might be doable. I took a look when Jupiter was low in the sky earlier this evening, just be fore it rotated out of view. It is definitely visible, but if it is an impact, it definitely isn't as big as the large SL-9 fragments. Incidentally, I was looking at it with exactly the same setup (scope (10 inch) and eyepiece) that I used for SL-9.
