Because Galileo is such a historic figure, NASA named a spacecraft sent to explore the planet Jupiter after him. And these astronomers back at his birthplace recently began mulling over the latest results for that historic mission to Jupiter. Among other things, the mission detected sulfuric acid on JupiterÂ's moon, Europa. Now, to hear Astronomers tell it, there are bacteria on earth that feed on sulfur, and that could be happening under EuropaÂ's icy surface.
If--mighty big if--but if that is true, could there be actual life there, too?
We donÂ't know. Which is why weÂ'll be returning to Jupiter, and elsewhere in the cosmos, repeatedly in years to come. Is there life out there? If there is, weÂ'll find it, sooner or later.
