Uranus's Largest Moon: Titania

Explanation: Titania's tortured terrain is a mix of canyons, cliffs, and craters. NASA's interplanetary robot spacecraft Voyager 2 passed the largest moon of Uranus in 1986 and took the feature picture. That the trenches of Titania resemble those on another moon of Uranus, Ariel, indicate that Titania underwent some violent surface event possibly related to water freezing and expanding in its distant past. Although Titania is Uranus's largest moon, it is only about half the radius of Triton - the largest moon of Uranus's sister planet Neptune, which itself is slightly smaller than Earth's Moon. Titania, discovered by William Herschel in 1787, is essentially a large dirty iceball that is composed of about half water-ice and half rock. There is recent speculation that radioactive heating melts some underground ice into oceans.

Wonderful analysis and animated recreation of M.C. Escher's "Picture Gallery" by 3B1B: https://www.youtube.com/watch?v=ldxFjLJ3rVY

The 2003 paper by De Smit and Lenstra who as number theorists were intimately familiar with elliptic functions ("doubly periodic complex functions") at the heart of the image https://pub.math.leidenuniv.nl/~smitbde/papers/2003-de_smit-lenstra-escher.pdf

I grew up in Baarn where Escher lived for a while but only learned later that he lived on the same street! D'oh. Of course we were separated by 35 years.
