Never-before-seen temperature and ion density measurements reveal that the effect of Jupiter's moons on its aurora are more complicated than scientists thought.

Observations from the James Webb Space Telescope show how Jupiter reacts to its moons through auroral footprints, plasma interactions, and rapid electron flows detected in infrared measurements.

Turn a telescope to the eastern sky in the hours following midnight on Nov. 5 to see two colossal shadows darken the cloud tops of the gas giant Jupiter as the Galilean moons Io and Europa pass ...

There’s no mistaking Jupiter in the sky these Pottsville winter evenings, rising in the southeast as evening twilight ends. In fact you should be able to easily see it long before twilight fades.

New research suggests that Jupiter’s icy moons may have formed with complex organic molecules already embedded in their building blocks.

When did Jupiter’s Galilean moons first contain the ingredients for life? This is what complementary studies published in The Planetary Science Journal and Monthly Notices of the Royal Astronomical ...

This first-ever complete map of Jupiter's volcanic moon Io released on March 19, 2012, was created using data and images from NASA's Galileo spacecraft, (which studied Jupiter and its moons between ...

A comet from another star system will swing by Mars on Friday as a fleet of spacecraft trains its sights on the interstellar visitor. We already know a decent amount about how planets form, but moon ...
