New research suggests a giant impact may not have been responsible for the formation of Jupiter's core. Most planetary scientists thought that a colossal collision with an early planet containing half ...

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon ...

Jupiter is the largest planet in our solar system (so large, in fact, that some scientists think it might have even consumed other worlds), a gas giant so massive that it shaped the orbits and ...

A pair of astrophysicists with Aix- Marseille Université, CNRS, and Institut Universitaire de France have developed a new theory about the formation of Jupiter's largest moons. In their paper ...

Over four billion years ago, the solar system was a wild and dangerous place. Swirling clouds of dust and gas slowly turned into the planets we know today. One giant, Jupiter, grew quickly and changed ...
