Jupiter's Moon Europa May Have Fish

National Geographic reports that Jupiter's moon, Europa, may have the necessary conditions for fish-sized life to live in its vast, dark oceans:

In the oceans of a moon hundreds of millions of miles from the sun, something fishy may be alive—right now.

Below its icy crust Jupiter's moon Europa is believed to host a global ocean up to a hundred miles (160 kilometers) deep, with no land to speak of at the surface.

And the extraterrestrial ocean is currently being fed more than a hundred times more oxygen than previous models had suggested, according to provocative new research.

That amount of oxygen would be enough to support more than just microscopic life-forms: At least three million tons of fishlike creatures could theoretically live and breathe on Europa, said study author Richard Greenberg of the University of Arizona in Tucson.
