The summer solstice occurred at 5:14 ET this morning, so last night was Midsummer Night. A couple of the larger moons of Uranus are named for characters from Shakespeare’s play A Midsummer Night’s Dream: Titania, and Oberon. Titania is the largest of the planet’s moons.

Titania’s tortured terrain is a mix of valleys and craters. Voyager 2 took this photograph in 1986. The long valleys indicate that Titania underwent some unknown tumultuous resurfacing event in its distant past. Titania is essentially a large dirty iceball composed of a roughly 50/50 mix of water ice and rock. It was discovered by William Hershel in 1787.
