Titania is Uranus's biggest moon, about 1,600 km wide.
Canyons hundreds of kilometres long split its surface. Scientists think they formed as its insides froze and expanded, cracking the crust.
William Herschel found it in 1787, six years after he found Uranus itself.
It's named after the queen of the fairies in Shakespeare's A Midsummer Night's Dream.
