Title:
Io: The Prometheus Plume
Explanation:
Two sulfurous eruptions are visible on Jupiter's volcanic moon Io [ http://antwrp.gsfc.…] in this color composite Galileo image [ http://galileo.ivv.…]. On the left, over Io's limb, a new bluish plume rises about 86 miles above the surface of a volcanic caldera [ http://www.op.dlr.d…] known as Pillan Patera. In the middle of the image, near the night/day shadow line, the ring shaped Prometheus plume is seen rising 45 miles above Io [ http://cass.jsc.nas…] while casting a shadow to the right of the volcanic [ http://volcano.und.…] vent. Named for the Greek god [ http://edweb.sdsu.e…] who gave mortals fire, the Prometheus [ http://adhocalypse.…a.coulter/hot/promet h.htm ] plume is visible in every image ever made [ http://galileo.ivv.…] of the region dating back to the Voyager flybys [ http://nssdc.gsfc.n…object_page/vg1_1636 836.html ] of 1979 - presenting the possibility that this plume has been continuously active [ http://www-a.jpl.na…] for at least 18 years. This image was recorded on June 28 at a distance of 372,000 miles.
