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 …

Astronomers using NASA’s James Webb Space Telescope have spotted 300 mysterious objects that may be some of the universe’s earliest galaxies. If confirmed, their existence could reshape our understanding of how galaxies first formed. (Artist’s concept). Credit: SciTechDaily.com Drawing on observations from NASA’s James Webb Space Telescope, researchers at the University of Missouri have identified 300 unusual candidates for early …

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 …

For the first time, scientists have used the James Webb Space Telescope (JWST) to study the origins of a bizarre, record-breaking radio signal that flashed past Earth earlier this year. Tracking the bright radio burst to the edge of a galaxy some 130 million light-years from Earth, the researchers used JWST’s infrared eye to identify a powerful explosion of energy …

A team of scientists at the Southwest Research Institute, using photography commissioned from NASA’s James Webb Space Telescope, have discovered a previously unknown moon in our solar system that’s in a “nearly circular” orbit around Uranus. Just six miles in diameter, our little neighbor is so small that no telescope has been powerful enough …

Recently, the Hubble Space Telescope captured a before-and-after image of a star exploding brightly. With the images one year apart, the contrast shows how bright a supernova is, and how that brightness fades over time. What is it? The supernova explosion, designated as SN 2018gv, is found in the spiral galaxy NGC 2525. According to NASA, Hubble began observing the …

Two of the solar system‘s most famous asteroids, Bennu and Ryugu, may be fragments of a single massive “parent” asteroid that was smashed to pieces billions of years ago, new data from the James Webb Space Telescope (JWST) reveals. If true, the sibling space rocks — which have both recently been visited by spacecraft that successfully returned samples of them …

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. …
