The result may have been comparable to Jupiter's moon Io, the most volcanic body in the solar system. Early in the history of the solar system, a massive protoplanet plowed into a young Earth.

For example, Pappalardo said, Europa is gravitationally locked with its neighboring moon Io, which has an eccentric orbit around Jupiter. This means Io may be pushing and pulling on Europa in ...

Jupiter will soon end its brilliant year-long showing on consecutive evenings with a rendezvous with an exceedingly thin and very young crescent moon. Indeed, for the first opportunity on Tuesday ...

Look for Jupiter to the upper left of the crescent. Since the waxing moon follows the sun, the best time to find it is starting about 30 minutes after sunset low in the northwestern sky.

Get Instant Summarized Text (Gist) Jupiter was about twice its current radius and possessed a magnetic field roughly 50 times stronger than today around 3.8 million years after the solar system's ...

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 ...

The images from NASA’s Galileo spacecraft include the highest-resolution view yet of Io, one of Jupiter’s large moons. A bumpy plain in that image has dark and light patches interspersed like ...

These pinpricks of light are actually Jupiter's four largest moons, now known as the Galilean moons: Io, Europa, Ganymede, and Callisto. Many of these celestial orbs are as remarkable as Jupiter ...

which will be studying several of Jupiter's icy moons, gases from the volcanic moon Io and Jupiter itself. Having two UVS instruments in the Jupiter system at one time offers complementary science.
