Using NASA's James Webb Space Telescope, a team led by the Southwest Research Institute (SwRI) has identified a previously unknown moon orbiting Uranus, expanding the planet's known satellite family to 29.

“No other planet has as many small inner moons as Uranus, and their complex inter-relationships with the rings hint at a chaotic history that blurs the boundary between a ring system and a system of moons,” SETI Institute researcher Matthew Tiscareno said in a statement for NASA.
