While the SETI Institute is investigating interstellar space for extraterrestrial life, we may find it in our own cosmic backyard. It is unlikely to be anything other than microbial life, but even that would be a seismic, perception-altering discovery.

NASA just launched a spacecraft the size of a basketball court towards Jupiter's moon Europa. Here's what will happen over the next 10 years.

NASA launched a spacecraft from Florida on Monday on a mission to examine whether Jupiter's moon Europa has conditions suitable to support life, with a focus on the large subsurface ocean believed to be lurking beneath its thick outer shell of ice.

A NASA spacecraft has set sail for Jupiter and its moon Europa, one of the best bets for finding life beyond Earth.

The spacecraft will be NASA's first dedicated to studying a distant ice-covered moon in our solar system to determine whether it could be habitable for life.
