JWST images have now revealed a 29th moon orbiting the planet that is not visible here.

The spacecraft returned with images of 11 new moons, on top of the five that were already known. Since Voyager, astronomers using the Hubble Space Telescope and ground-based telescopes have spotted other tiny moons—ones as little 12 to 16 km in diameter. But “this one was so small and so faint and so close to the bright ring system around Uranus that we missed it,” Hammel says.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by .

This composite image shows the moon, designated S/2025 U1, as well as 13 of the 28 other known moons orbiting the planet.NASA, ESA, CSA, STScI, M. El Moutamid (SwRI), M. Hedman (University of Idaho)A team led by the Southwest Research Institute detected the moon in images captured by the high-resolution Near-Infrared Camera on the James Webb Space Telescope (JWST) during a series of 10 40-minute-long exposures. “The cameras on [JWST] are very sensitive,” Hammel says. “They were designed to see the faintest galaxies in the universe,” as well as faint things that are close to very bright ones (such as the planet Uranus). NASA today via a blog post.“One of the reasons this moon is interesting is that it’s very close to the main ring system,” Hammel says. Unlike Saturn’s rings, which are packed together, Uranus’s rings are more like Hula-Hoops, with lots of separation between each. The rings cluster between a main inner system and a faint outer one, Hammel says, and researchers speculate that the rings are sculpted by the planet’s little orbiting moons.There are still many questions about the new minuscule moon for astronomers to explore: How does it compare with other moons? What is its color and composition? JWST might help answer a few of these questions. But regardless of what comes next, the discovery shows “how we can extend the horizons of our knowledge, even in our own solar system, using an advanced telescope like JWST,” Hammel says. “And it helps us get a better understanding of what drives the phenomena in our solar system—like “‘What is crafting that ring system around the planet Uranus?’”Rights & PermissionsAndrea Tamayo is the current newsletter and engagement intern at Scientific American and a freelance science writer.
