Using some of the largest telescopes in the world, including the Subaru Telescope, a team of astronomers discovered three new natural satellites orbiting the outermost planets in our solar system—one around Uranus and two around Neptune. One of the new moons, initially detected by the Subaru Telescope, is the faintest moon ever discovered by ground-based telescopes.
