And so it was, when I reported on January 21 that fish were found living in an isolated corner of the ocean beneath 740 meters of ice in Antarctica: People asked what this might mean for finding life on distant worlds such as Europa, a moon of Jupiter that very likely harbors an ocean of liquid water beneath a crust of ice.

Beneath an ice layer about 10 to 15 miles (15 - 25 kilometers) thick, the moon is thought to harbor a liquid water ocean, possibly warmed by geologic processes originating in the planet's core.

Europa is thought to have an ocean of water beneath its icy shell.

The floating ice in the channel has ample room beneath it for ocean water to flow in.

If the water remained in the channel, the water would eventually cool to a point where it was not melting much ice, but the channels allow the water to flow out to the open ocean and warmer water to flow in, again melting the ice shelf from beneath.
