Title:
Galileo, Cassini, and the Great Red Spot
Explanation:
Imagine a hurricane that lasted for 300 years! Jupiter's Great Red Spot indeed seems to be a giant hurricane-like storm system [ http://www.coaps.fs…] rotating with the Jovian clouds. Observed in 1655 by Italian-French astronomer Jean-Dominique Cassini [ http://www.jpl.nasa…] it is seen here over 300 years later - still going strong - in a mosaic of recent Galileo spacecraft images [ http://www.jpl.nasa…]. The Great Red Spot is a cold, high pressure area 2-3 times wider than planet Earth. Its outer edge rotates in a counter clockwise direction [ http://bang.lanl.go…] about once every six days. Jupiter's own [ http://seds.lpl.ari…] rapid rotation period [ http://www.kalmbach…] is a brief 10 hours. The Solar System's largest gas giant planet [ http://antwrp.gsfc.…], it is presently well placed [ http://antwrp.gsfc.…] for evening viewing [ http://www.kalmbach…]. (APOD thanks to Alan Radecki for assembling a preliminary mosaic from the Galileo imagery!)
