Using data gathered by NASA's Juno Jupiter orbiter, scientists estimate that Europa's ice shell is about 18 miles thick — which could make it hard for nutrients to get down to its buried ocean.

A new finding of ammonia on the icy surface of Jupiter's moon Europa could have important implications for the search for extraterrestrial life.

But the real truth is that alien life on other planets could be even stranger than floating balloons or amorphous organisms ...

Researchers from NASA’s Jet Propulsion Lab (JPL) recently detected the presence of ammonia — a nitrogen-bearing compound crucial to supporting life — on ...

The NASA Juno mission has given deeper insights into the possible alien life on Jupiter's moon, Europa, and how it could lie ...

Europa stands out among Jupiter's moons, thanks to its remarkably smooth ice shell, which scientists believe conceals a global ocean of liquid water, perhaps twice as deep as Earth's oceans. In late ...

The Science: Europa has been considered as a top contender for alien life for even longer than Enceladus, thanks to its massive under-ice liquid water oceans. It also displays water vapor plumes ...
