Jupiter

The Hubble Space Telescope has seen Jupiter's Great Red Spot oscillating in width as it drifts around the planet. Could this be related to its overall shrinking?

New simulations show that Jupiter's massive moon Ganymede was knocked off its axis when it was struck by a roughly 90-mile-wide asteroid around 4 billion years ago. The colossal collision was likely one of the biggest asteroid impacts the solar system has ever seen.

Vivid clouds swirl across Jupiter's skies like colorful brushstrokes in a new photo from NASA's Juno spacecraft.

New infrared images showcase "fire-breathing" lakes all across the surface of Jupiter's volcanic moon Io.

Astronomers using the James Webb Space Telescope (JWST) have spotted a previously unseen structure in the atmosphere above Jupiter's famous Great Red Spot.

Astronomer Giovanni Cassini observed Jupiter's 'Permanent Spot' in 1665, but new research suggests it's a different vortex from today's Great Red Spot.

Astronomers using the Large Binocular Telescope in Arizona have taken a close-up picture of Jupiter's volcanic moon Io that rivals similar photos taken from space.

The Juno spacecraft, which orbits Jupiter, has been imaging the giant planet's moon Europa and spotted apparent movement in its icy crust.

NASA's Juno spacecraft has spotted the elusive fifth moon of Jupiter transiting the giant planet's Great Red Spot, giving astronomers a rare view of this small but intriguing natural satellite.

The great planetary instability, which saw Jupiter and the other gas giants wander chaotically through the solar system, coincides with the collision that formed Earth's moon. Could the two events be linked?
