Title:
Oceans Under Jupiter's Moon Ganymede? Title Oceans Under Jupiter's Moon Ganymede? Title
Explanation:
The search for extraterrestrial [ http://www.seti.org/] life came back into our own Solar System [ http://www.seds.org…] last week with the announcement [ http://www.jpl.nasa…] that there may be liquid oceans under the surface of Jupiter [ http://antwrp.gsfc.…]'s moon Ganymede [ http://www.jpl.nasa…]. Ganymede [ http://antwrp.gsfc.…] now joins Callisto [ http://www.jpl.nasa…] and Europa [ http://www.jpl.nasa…] as moons of Jupiter [ http://www.solarvie…] that may harbor seas of liquid water under layers of surface ice [ http://antwrp.gsfc.…]. The ocean hypothesis surfaced as an explanation for Ganymede's unusually strong magnetic field [ http://www.igpp.ucl…]. Ganymede, the largest moon in the Solar System, also has the largest measured magnetic field [ http://www-spof.gsf…] of any moon. Some exobiologists [ http://exobiology.n…] hypothesize that life may be able to emerge [ http://www.etext.or…] in such an ocean, much as it did in the oceans of ancient Earth [ http://wwwcatsic.uc…]. Above [ http://photojournal…], a frame from a computer simulation [ http://photojournal…] shows what it would look like to fly over [ http://antwrp.gsfc.…] the surface of Ganymede, as extrapolated from photographs of the grooved moon [ http://antwrp.gsfc.…] taken by the robot spacecraft Galileo [ http://www.jpl.nasa…] currently orbiting Jupiter.
