Jupiter's Shadowy Ring Behavior
http://sciencenow.sciencemag.org/cgi/content/full/2008/430/2

By Phil Berardelli
ScienceNOW Daily News
30 April 2008

Jupiter's faint rings might seem plain-Jane compared with Saturn's spectacular disks, but
they have vexed astronomers for years, because the outer ring is lopsided. Now researchers
report that the ring was pulled out of round by a tug of war between Jupiter's powerful
magnetic field and the energizing effects of sunlight. The discovery should improve
understanding of the forces that shape the rings around Saturn and other planets.

  Jupiter - GRS changes         


Author: canopus56
Date: Apr 29, 2008 16:18

Rogers, JOhn H. Feb. 2008. The accelerating circulation of Jupiter's
Great Red Spot. J. Br. Astron. Assoc. 118(1):14-20
http://www.britastro.org/journal/118-1.htm

Summarized and abstracted from the above article.

Since about 1949, the characteristics of the GRS changed as follows:

1) Length: ~28 degs to 16-18 degs, the smallest ever recorded. 1 deg
= 1160km.

2) Circulation period of vortex within GRS: 12 to 4.5 days

3) Wind speeds as measured by amateur CCD and spacecraft imaging of
streaks and spots within the GRS:

1979 Voyager 1 110-135 m/s
1979 Voyager 2 110 m/s
1996 Galileo 115-135 m/s
2000 Galileo 145-165 m/s
ALPO 2001-2002 100 +-8 m/s
ALPO 2002-2003 89-97 m/s
BAA 2006 112 m/s (this paper)

100 meters per second equals 360 kilometers per hour

fiercely, but the massing evidence from paleontology, genetics,...
