Juno measures oxygen production on Europa

Using NASA’s Juno spacecraft, scientists have calculated the rate of oxygen production on Jupiter’s moon Europa — the first time any spacecraft had directly measured charged oxygen and hydrogen particles from the moon’s atmosphere.

NASA's Juno Orbiter Captures Stunning Images of Jupiter's Moon Io

On February 3, 2024, NASA’s Juno spacecraft made a second close flyby of Io, the third largest of Jupiter’s moons. We were able to see a volcunic erruption there like never before.

Webb pinpoints a high-speed jet stream on Jupiter

Researchers using the NASA/ESA/CSA James Webb Space Telescope's NIRCam (Near-Infrared Camera) have discovered a high-speed jet stream sitting over Jupiter's equator, above the main cloud decks.

NASA’s Webb Finds Carbon on Jupiter’s Moon Europa

Now, using the James Webb Space Telescope, astronomers have found carbon on Europa’s surface, which likely originated in this ocean. The discovery signals a potentially habitable environment in the ocean of Europa.

Giant swirling waves at the edge of Jupiter's magnetosphere

NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere. 

Scientists Unravel the Mystery Behind Jupiter's Colour-Changing Stripes

Recent research shows that the changes in Jupiter's magnetic field are causing these mysterious colour shifts. 

NASA's Lucy Mission Snaps its First Views of Trojan Asteroid Targets

Some of the asteroids NASA's Lucy mission will visit are still more than 330 million miles away from the spacecraft, but despite the great distance and the comparatively small sizes, Lucy caught views of four of its targets in late March.

Jupiter Overtakes Saturn as The Planet With The Most Known Moons

Astronomers have counted 12 previously unknown moons in orbit around our Solar System's biggest planet, bringing the known total to 92, and leaving Saturn, with its measly count of 83, in the dust.

Heat wave on Jupiter, from its aurora

Researchers had discovered a “heat wave” extending across 10 Earth-diameters in the atmosphere of our solar system’s biggest planet, Jupiter. In other words, Jupiter’s atmosphere is hundreds of degrees hotter than previously thought.

Jupiter's Moon Europa Has Signs of Liquid Water

Strange double ridges on the surface of Jupiter's ice moon Europa could be signposts to shallow reservoirs of water. 

Europa Could Be Pulling Oxygen Down Below the Ice To Feed Life

Jupiter's moon Europa is a prime candidate in the search for life. The frozen moon has a subsurface ocean and the new research shows that the moon is pulling oxygen down below its icy shell.

First 3D View of Jupiter Atmosphere

New findings from NASA's Juno probe orbiting Jupiter provide a fuller picture of how the planet's distinctive and colorful atmospheric features offer clues about the unseen processes below its clouds.

Something big Just hit Jupiter

The impact on Jupiter was reported by both amateur and professional astronomers. The object’s diameter is estimated at 20 meters and it is believed to be the remnant of a larger comet or asteroid.

Evidence of water vapor at Jupiter's moon Ganymede

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.

Titan's Largest Methane Sea is Over 100 Meters

Kraken Mare, a sea of liquid methane on Saturn's moon Titan, is at least 100-m deep near its center, according to a recent analysis of Cassini's data.
