Two new moons have been discovered orbiting Jupiter, bringing the total number of natural satellites orbiting the gas giant ...

While the moons are passing in front of Jupiter, they also cast their shadows on the planet's cloud deck below them. These shadows may be observed with telescopes of at least 90mm aperture ...

Growing moons. In general, researchers agree that the four Galilean moons — Io, Europa, Ganymede and Callisto — probably formed from a disk of gas that surrounded Jupiter in its infancy.

Europa is one of Jupiter’s four large Galilean moons. And in a paper published Monday in the Astrophysical Journal, Dr. Batygin and a co-author, Alessandro Morbidelli, ...

The Galilean moons are still the largest, and probably the coolest, of Jupiter's moons. Io is the most volcanically active place in the solar system, with 250-mile-high lava spurts possibly fed by ...

Finally, this same process repeated, leading to the sequential creation of Jupiter’s four Galilean moons, working from inside to out. According to Batygin, Jupiter’s innermost moons — Io and Europa, ...

A brief history of Jupiter’s Galilean moons, and how to observe them These remote satellites have revealed scant details to earthbound observers for more than 400 years, and offer a great ...

For decades scientists have struggled to understand the strange density differences in Jupiter’s four Galilean moons—which, in order from closest to the planet to farthest from it, are Io ...

Researchers reported auroras around Jupiter’s two largest Galilean moons for the first time and found new features in the auroras of volcanic Io and icy Europa. Share full article. 15.

Scientists have discovered 12 previously unknown moons orbiting Jupiter, and one of them is a real oddball. While hunting for the proposed Planet Nine, a massive planet that some believe could lie ...
