Astronomers have discovered that the "dark sides" of Uranus' largest moons aren't where they originally thought — and in some cases are on the complete opposite sides of the icy satellites than expected.
Uranus has 28 confirmed moons, including five major moons. The closest of these large satellites is Miranda, followed by Ariel, Umbriel, Titania and Oberon — all named after characters from plays written by William Shakespeare. These icy bodies, which range from 293 to 980 miles (472 to 1,578 kilometers) wide, are all "tidally locked" to Uranus, meaning that the same half of the moon always faces the planet, similar to how Earth's moon orbits our planet.
