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.

“Our findings suggest that Jupiter’s moons did not form as chemically pristine worlds,” Mousis said. “Instead, they may have accreted, or accumulated, a significant inventory of COMs at birth, ...

Using the Webb telescope, scientists discovered an unexpectedly cold, dense region within Io’s auroral footprint in Jupiter’s northern lights.

Jupiter’s icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international ...

A NASA mission to explore a Jupiter moon believed to be one of our galaxy's most promising locations to search for life-supporting conditions is at long last underway. The Europa Clipper launched ...

A massive NASA mission to explore if one of Jupiter’s moons could support life launched Monday morning from Florida. The Europa Clipper spacecraft lifted off aboard SpaceX’s Falcon Heavy rocket bound ...

The largest of all planets in the Solar System, Jupiter is a gas giant with a mass that is twice the size of all other planets combined. You may have learned in your school science text that if it ...

Ganymede's auroras splinter into small, bright patches — structures that mirror features seen in Earth's own auroral displays ...

Astronomers have discovered 12 new moons around Jupiter, putting the total count at a record-breaking 92. That's more than any other planet in our solar system. Saturn, the one-time leader, comes in a ...

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.
