Jupiter's "Mini-Me" Solar System Grows

An anonymous reader writes "University of Hawaii's robotic telescopes have discovered 8 new moons for Jupiter, thus bringing its mini solar system to 48 total. No one knows how Jupiter dissipates the energy of these likely asteroid captures, unless it once had a massively larger atmosphere. Indeed, its ion cloud today seems to spell doom for what Sir Arthur C. Clarke indicated, is another reason to avoid probing life on Europa. ('All these worlds are yours--except Europa. Attempt no landings there.'-- 2010: Odyssey Two). As an aside, one of those NASA sites seem technically to be doing text-to-speech in a very familiar-sounding, Stephen Hawkings version [MP3] of those articles."
