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."

Re:Europa's not the only possibility

[Soft]

So ruling out Europa doesn't mean that there is no life in the Jovian system.

Besides, I still can't see how the Europa torus could hamper life there. On the surface, yes, but that was pretty much already known. Life would be underwater, in an ocean tens of kilometers deep, the radiations won't penetrate that far. So don't rule out Europa.

We should look for life on Europa but I thing it is not the right moment. We lack technical capabilities for now. A probe looking for life on Europa should travel the distance between Earth and Jupiter, land on Europa, burn its way through a very thick layer of ice (maybe 10 - 20km, swim autonmously trough a dark ocean probing for life, find its way up to the surface and transmit data back to earth. I think this is out of our technicak capabilities for now. Maybe latter.
