These large jupiter-sized planets are not like earth or mars. They are gaseous, so if they support life I assume it is in a much a different form than what we can imagine.

It seems one of the reasons that hubble is going to die is because Bush pushing this moon/mars thing, and starving the rest of nasa. This whole manned mars trip is retarded. Hubble has provided us with so much more valuable information, the strongest telescope known to man, and Bush has no clue.
