Updating a model developed during the Voyager flybys will enable better mission planning and a deeper understanding of Juno data.
The electron density peaks well after the activity of the moon’s distinctive south polar ice plume reaches its maximum, but the cause of the lag remains puzzling.
Decades of research have illuminated how Io and Europa shape—and are shaped by—Jupiter’s giant magnetosphere.
A planet’s magnetic field usually protects its atmosphere from being blown away by its star. But new research suggests Mars’s weak magnetic field may have helped its atmosphere escape.
Aurorae once classified by human eyes are now being sorted by machines. The change may help astronomers understand how the mysterious features are powered.
Japan’s Hisaki satellite takes measurements of faint oxygen emissions from Io.
When it comes to Saturn’s space environment, summer wins over winter in controlling the periodic flows of electrically charged particles and magnetic fields.
The NASA spacecraft has taken images of Jupiter’s powerful aurora dancing around its poles, revealing never-before-seen details in their structure.
The unexpected character of the beams, revealed by NASA’s Juno spacecraft, suggests that the processes that produce Jupiter’s auroras are unlike those on Earth.
The editor of a new book describes how a unique combination of the monograph and video show that a four-decade old paradigm in solar-terrestrial physics is changing.
