QUOTE (tedstryk @ Aug 4 2005, 08:06 PM) Very nice. I think one the most evocative images of Jupiter is a HST image (below) of the aurora where you can see the flux tube footprints of the largest moons. The footprint of Io is the left. Are we gonna see something similar on Saturn with Titan/others or was that effect particular to the Jupiter system and the galilean moons?

JOVIAN DREAMS
- Solar Wind Whips Up Auroral Storms On Jupiter And Saturn http://www.spacedaily.com/reports/Solar_Wi...And_Saturn.html Leicester, UK (SPX) Mar 31, 2006 - Two new studies of auroras on Jupiter and Saturn have challenged current thinking about the processes that control the biggest light-shows in the solar system – it turns out the forces at work are the same that produce polar auroras on Earth. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Years and years ago, at the time of the Pioneer 10 and 11 encounters, the Io flux-tube (and co-orbital atmospheric torus) were widely described. At the time, Saturn's much smaller, though still huge, magnetosphere was described as being unlikely to have similar goings-on due to the ring material. Of course, since then we found out that Jupiter also has rings, but you'd think that Saturn's ring system is so much more extensive than that of Jupiter that it would indeed eat flux-tubes for breakfast.

Nice recent URLs on Saturn's auroras (which are indeed considerably different from thsoe of both Earth and Jupiter):
