Two new moons orbiting Uranus were announced in Nature magazine.
A team of scientists and astronomers from Cornell University discovered the moons on October 31, 1997, using a 200-inch (5.1 m) Hale telescope at Mount Palomar, California. The two moons, later named Caliban and Sycorax after characters from Shakespeare’s Tempest, were the first two moons discovered in irregular orbits around Uranus.
