Callisto, the third largest moon in the entire solar system, orbits Jupiter from about 1.2 million miles away. The rocky ...

We believe Mars may once have had oceans and sky, but lost them from a lack of a magnetosphere. How does this happen, and how can we create a magnetosphere for Mars so we can terraform and live on it?

There was a lot, aesthetically, to latch onto: the violent, ascension-like episode, the drama of bestowed-upon immortality, the idea of an attractive young man. Though Ganymede’s ordeal struck me as ...

Alas, the miracle could not last. The solar storms were heating Earth's upper atmosphere, causing it to inflate and increase ...

The good news is that, for decades, scientists have only detected these chirps some 32,000 miles from Earth, meaning they only occur near planets, moons (shoutout to Ganymede), or anything else with a ...

Loki Patera is 202 kilometres (126 mi) in diameter, covers 20,000 sq km (7,700 sq mi), and was the largest volcanic feature ...

Juno’s findings have already transformed how we view Jupiter, uncovering a wildly dynamic atmosphere, a powerful magnetosphere, and moons like Europa and Ganymede with stories of their own. Its ...

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 ...

These far-flung chorus waves were discovered using data from NASA’s Magnetospheric Multiscale (MMS) mission, which uses four identical satellites for studying the Earth’s magnetosphere.

A good example is the Jupiter Icy Moons Explorer (JUICE) mission, which will make detailed observations of the gas giant and its three large ocean-bearing moons Ganymede, Callisto and Europa.
