These surprising effects, detected in observations from the James Webb Space Telescope , include a cold spot in Jupiter's ...

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.

Back in September 2023, a research team chasing Jupiter's northern lights using the James Webb Space Telescope made the first spectral measurements ever of the infrared auroral footprints created by ...

“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.

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 ...

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.
