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.

Jupiter, the biggest planet in our solar system, is not as big as we thought. For more than half-a-century, astronomers thought they had a good idea of the gas giant's shape and size. Now, a fresh ...

While Jupiter's main aurora has a great deal of hot materials, a snapshot showed a cold spot in Io's auroral footprint.

NASA's spinning spacecraft studying the satellites of the solar system's largest celestial body (aside from the sun), may already be switched off, but the space agency won't say. The Juno probe ...

Many of us know Jupiter as the solar system’s largest planet, and while it still is, recent findings from NASA’s Juno mission reveal data that the planet is a little smaller and more "squashed" than ...

Stargazers will soon have an opportunity to view six planets in alignment in the night sky, according to NASA. Mercury, Venus ...

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

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.

Six planets are set to align on Saturday, creating a planetary parade that will be visible to sky-gazers across the globe.

The measurements from NASA's Juno orbiter mark the first time that the size and shape of Jupiter has been evaluated in more than fifty years. NASA's Pioneer and Voyager missions made observations of ...
