NASA's Webb telescope has discovered a 29th moon orbiting Uranus, a tiny object approximately 10 kilometers wide. Its small size and faintness explain its previous elusiveness, even during Voyager 2's flyby. Researchers suggest many more undiscovered moons may exist in Uranus's system, highlighting the complex interplay between its moons and rings. The new moon, yet to be named, will be officially designated by the International Astronomical Union.
