Many surprises! Jupiter not uniform below clouds! Giant ammonia plume comes up from equator! Core diffuse, possibly dissolving! Magnetic field up close has surprised! Congrats on the amateur images everyone! -------------------- Space Enthusiast Richard Hendricks

Is there any likelihood that a video of Scott Bolton's AAS231 plenary session lecture on results from the Juno mission will be publicly released?
I read something on the AAS website to the effect that videotapes of ordinary meeting sessions are posted on the AAS members' site as a "member benefit," but I was hoping that the video of this lecture wouldn't be restricted to members. |

Some people have posted on Twitter photos of and comments about Bolton's Jan. 9 lecture. Some of the Twitter quotes are ambiguous or cryptic, but there are some definite and stunning new discoveries.
• Cyclones circling Jupiter's north pole form an octagon, whereas the south pole shows a pentagon. • Jupiter's magnetic field twice as strong as expected. • More lightning than expected. • Odd-numbered harmonics in gravitational field expected to be zero, but aren't. • Impossible for one or two entry probes to provide the big picture. (Implications for future Saturn, etc. missions.) • Aurorae somehow switch off at night. • Great Red Spot has roots that reach much more deeply (>350 km) into atmosphere than zones and belts do. • All heavy elements enriched (over solar) by same amount, except water is depleted. (Galileo Probe result?) Overall: "Everything" we thought we knew about Jupiter's interior before Juno was wrong. I note from IR images that most polar cyclones have swirling hot/cold centers, but three at south pole cold only. As mentioned in previous releases: • Larger, fuzzy core instead of small, compact one or none. • River of gases rich in ammonia flowing from depths up to surface near equator. Profoundly spectacular video showing a dive through the Great Red Spot: https://www.youtube.com/watch?v=-lsKC1NVaqw A long approach video shows Galileans orbiting "half" Jupiter for (several?) weeks. My sense is that this talk seems to have contained more significant discoveries concerning one world than we've seen in a long time except maybe Pluto; that's rather stunning when one considers that this is the sixth mission dedicated to Jupiter, and moreover, that the mission isn't half over. |
