Plasma waves, multiple shock regions and lightning far more powerful than Earth's are rewriting what scientists know about the solar system's largest planet.

A trio 12.5 billion light-years away includes two black holes just 620 light-years apart and one growing faster than theory predicts.

A single frame from New York shows Earth's Moon and all four Galilean satellites, days after the Moon passed directly in front of Jupiter.

New infrared views of NGC 7129 show protostars firing jets that stretch eight light-years, giving astronomers their clearest look yet at a busy stellar nursery in Cepheus.

Grains in one of the oldest known meteorites show magnetism worked alongside gravity in the first 200,000 years of the solar system.

Roman Space Telescope is in space and has detected starlight, but first images won't arrive until 2027; PRIMA far-infrared probe advances to Phase B.

A Jupiter-size world less than a million years old is orbiting far from its star, forcing theorists to rethink how giant planets are born.

The tiny centaur between Saturn and Uranus is the smallest known body with a ring system — and new Webb data show both rings shifting in opacity over just a few years.

The 728-foot-wide McGetchin crater formed in 2024 when a building-sized object struck the Moon, the largest newly formed crater ever found.
