Using data collected by NASA's Juno spacecraft as it flew past Jupiter's highly volcanic moon Io in late 2023 and again in early 2024, a Southwest Research Institute-led team identified electrons with ...

Jupiter's second-largest moon has more impact ... This presented a challenge, because of Triton's intense ionosphere, which is the last layer of the atmosphere before space begins.

James Webb Space Telescope captures Neptune’s auroras, revealing new details about its atmosphere and magnetism.

"It was so stunning to not just see the auroras, but the detail and clarity of the signature really shocked me." ...

An artificially colored view of Jupiter as seen in ultraviolet light ... of mixing generated by a vortex higher up in the planet's ionosphere. These dark UV ovals also appear periodically at ...

New evidence from an old NASA mission supports the theory that Jupiter's moon Callisto is in fact an ocean world.

A new study has strengthened the belief that one of Jupiter's moons might be hiding ... which researchers believed could be from its ionosphere – a strong ion layer surrounding it – or from ...

a Southwest Research Institute-led team identified electrons with energies enhanced by processes in the region connecting the moon to Jupiter’s ionosphere, called an Alfvén wing. A paper ...
