New research suggests there may be a narrow window of possibility for life to persist on the icy moons of the outer solar system.

Io, Europa, Ganymede and Callisto are, like Earth’s Moon, relatively large, spherical complex worlds. Two previous NASA missions have sent spacecraft to orbit the Jupiter system and collected ...

The Europa Clipper launched Monday afternoon aboard a SpaceX Falcon Heavy rocket, which is designed to help propel the spacecraft on a six-year journey to reach its namesake moon, an icy ocean world.

To make these lander missions happen, NASA’s Jet Propulsion Laboratory team has been working on a robot that could handle the search for life and already tested it on the Matanuska Glacier in Alaska. ...

One of Jupiter’s 95 known moons, Europa is almost the size of our own moon. It’s encased in an ice sheet estimated to be 10 miles to 15 miles or more (15 kilometers to 24 kilometers) thick.

The icy surface of Jupiter 's moon Europa appears to be constantly changing, new data from the James Webb Space Telescope has revealed. This phenomena, the team explained, is heightened in so-called ...

Europa Clipper will face a challenge once it reaches the planet's moon — exposure to radiation, since the moon is within Jupiter’s magnetic field.

The Europa Clipper launched Monday afternoon aboard a SpaceX Falcon Heavy rocket, which is designed to help propel the spacecraft on a six-year journey to reach its namesake moon, an icy ocean world.

Three weeks from now, NASA's Europa Clipper probe will lift off and embark on a long-awaited mission to study Jupiter's icy moon Europa, which scientists think is one of the most promising places ...

NASA’s Europa Clipper spacecraft launched at 12:06 p.m. Monday, beginning a nearly six-year, 1.8-billion-mile voyage to Jupiter, where it will study the frozen moon Europa, scanning below its ...

Europa is an icy ocean world—and NASA is finally going to explore it. For the first time, NASA is journeying to this mysterious moon to determine if it might be able to host alien life.

NASA has launched its Europa Clipper mission to the icy moon of Jupiter. Thought to contain an underground ocean and potentially habitable environment, Europa has long been a tantalizing target.
