explanation
A lava fountain shooting over a kilometer high has been discovered [ http://photojournal.jpl.nasa.gov/cgi-bin/PIAGenCatalogPage.pl?PIA02525 ] on Jupiter [ http://pds.jpl.nasa.gov/planets/welcome/jupiter.htm ]'s moon Io [ http://www.seds.org/nineplanets/nineplanets/io.html ]. The robot Galileo spacecraft [ http://www.jpl.nasa.gov/galileo/spacecraft.html ] orbiting Jupiter [ http://www.solarviews.com/eng/jupiter.htm ] photographed the volcanic eruption during its close flyby of the moon late last month [ http://www.spacescience.com/newhome/headlines/ast28nov99_1.htm ]. The fountain [ http://antwrp.gsfc.nasa.gov/apod/ap970623.html ] is visible in the above [ http://photojournal.jpl.nasa.gov/cgi-bin/PIAGenCatalogPage.pl?PIA02525 ] mosaic of images from the flyby [ http://IoFlyby.com/ ]. The lava [ http://antwrp.gsfc.nasa.gov/apod/ap991126.html ] plume [ http://antwrp.gsfc.nasa.gov/apod/ap970818.html ] was so bright it saturated Galileo's camera, and so has been digitally reconstructed in false color. The hot lava appears to be shooting from a 20-kilometer long canyon on Io's active surface [ http://antwrp.gsfc.nasa.gov/apod/ap990920.html ].
