Saturn And Jupiter Gain New Moons, Take Solar System Satellite Count To 442
The newly discovered moons are "irregular" satellites, meaning they are small (averaging about 3 km across) and have distant, often eccentric orbits.

James Webb Telescope Captures Rare Infrared Footprints of Io and Ganymede Inside Jupiter’s Auroras
Jupiter produces the strongest auroras in the solar system. These features glow brightly around its poles as energetic particles crash into the giant planet's atmosphere. New observations have now revealed that Jupiter's moons can disturb this glowing display in unexpected ways. Scientists using the James Webb Space Telescope (JWST) have identified...

NASA Finds Ammonia Compounds On The Surface Of Jupiter's Moon Europa
NASA's Galileo mission launched in 1989 and was operated by the Jet Propulsion Laboratory in Southern California.

NASA Finds a Crucial Life-Building Chemical on Jupiter’s Moon
Scientists studying archival Galileo spacecraft data have identified ammonia-bearing compounds on Europa for the first time. The ammonia appears along surface cracks, indicating recent transport from the moon’s subsurface ocean. Because ammonia contains nitrogen and degrades quickly under radiation, its presence strengthens Europa’s status as a...

Europa’s Hidden Ocean Could Be ‘Fed’ by Sinking Salted Ice; New Study Boosts Hopes for Alien Life
Europa, one of Jupiter’s icy moons, may have a more habitable ocean than once thought. New simulations show that dense, salt-rich ice on the surface can slowly sink through the moon’s thick ice shell and drip into the hidden ocean below. This process would deliver nutrients and oxidants over geological timescales, potentially sustaining conditi...

VLT’s GRAVITY Instrument Detects ‘Tug’ from Colossal Exomoon; Could Be Largest Natural Satellite Ever Found
Astronomers have spotted a subtle orbital wobble around the massive exoplanet HD 206893 B, hinting at the presence of a gigantic moon nearly half Jupiter’s mass. If confirmed, it would be unlike any moon known, potentially redefining how scientists distinguish between moons, planets, and brown dwarfs.
