Astronomers have long thought Ursa Major III, also called UNIONS 1, was a dark-matter-packed dwarf galaxy. But new simulations suggest it may instead be a compact star cluster bound by black holes and neutron stars. Located 30,000 light-years away, Ursa Major III contains just ~60 visible stars yet shows puzzlingly high stellar velocities. The new analysis explains th…

A team from the Southwest Research Institute has discovered a tiny new moon orbiting Uranus using NASA’s James Webb Space Telescope. The moon, called S/2025 U1, is just 6 miles (10 kilometers) wide, too small for Voyager 2 to detect during its 1986 flyby. This discovery brings Uranus’s total known moons to 29, with S/2025 U1 orbiting 35,000 miles from the planet…
