Astronomers using NASA’s James Webb Space Telescope have discovered a tiny new moon orbiting Uranus, a rare discovery that expands Uranus’ total known moons to 29, and the first inner one found in nearly 40 years. Provisionally named S/2025 U1, the hidden moon was first detected on February 2, 2025, and at just 10 kilometers (six miles) wide it is …

The James Webb Space Telescope has spotted a previously unknown moon orbiting Uranus, the solar system’s tilted seventh planet.  This new space discovery brings the ice giant world’s bevy of moons up to 29, a count that includes a yet-to-be-named moon discovered in 2023.  The newest moon likely escaped detection before now because it is so small. These findings, led …

A team of astronomers has found what appears to be a previously undiscovered moon orbiting Uranus. If confirmed, this finding would mean the gigantic blue-green ice planet would have 29 moons. The discovery was made using the James Webb Space Telescope (JWST), extending the instrument’s list of achievements and raising expectations that other new discoveries might be made within the …

A new discovery has just brought the total number of Uranus’s known moons to 29. In the space close to the icy planet, outside its ephemeral rings, JWST snapped a tiny object that no one had ever seen before, not even in data from the Voyager 2 probe that flew past Uranus at a close distance in 1986. It’s probably …

Facebook Tweet Email Link Astronomers using the powerful eye of the James Webb Space Telescope have spotted a previously unknown moon whirling around Uranus, according to NASA. The discovery boosts the number of moons known to be orbiting the ice giant to 29 — and there are likely more waiting to be found. The moon came to light through a …

The James Webb Space Telescope has spotted a never-before-seen moon orbiting Uranus, bringing the planet’s count of natural satellites to 29. The moon, for now dubbed S/2025 U1, is just 6 miles (10 kilometers) in diameter, which is why it was invisible to other telescopes and the Voyager 2 spacecraft when it made its 1986 flyby of the icy planet. …

Astronomers spotted a never-before-seen, bite-sized moon orbiting Uranus, bringing the ice giant’s follower count to 29. The moon is so small and faint—well below the detection threshold of NASA’s Voyager 2 probe—that scientists believe Uranus may host many more undiscovered, tiny moons. The moon, provisionally named S/2025 U1, first entered the view of the James Webb Space Telescope (JWST) on …

Circle Strafe NASA’s James Webb Space Telescope has spotted a tiny moon orbiting Uranus, expanding the number of the planet’s known satellites to 29. In early February, the space observatory’s Near-Infrared Camera (NIRCam) caught the minuscule and still-unnamed object orbiting the gas giant at a distance of 35,000 miles. “It’s a small moon but a significant discovery, which is something …

Astronomers using NASA’s James Webb Space Telescope have discovered a newfound moon orbiting icy Uranus, the seventh planet from the sun. The moon, known as S/2025 U1, is just 6 miles (10 kilometers) or so in diameter, which made it invisible to NASA’s Voyager 2 probe during its 1986 flyby of the planet, as well as rendering it undetectable by …
