Tycho

The Crater Tycho at full moon, exhibits an extensive ray system of impact ejecta,
however when illuminated obliquely the ray system disappears.

The crater was named after the Danish astronomer and alchemist, Tycho Brahe.  He is famous for his application of scientific method in the measurement and cataloguing of stars.  Johannes Kepler was one of his assistants.  He is also famous for losing part his nose in a duel and thereafter wearing a false nose made from silver, gold or brass.  Tycho Brahe died of mercury poisoning in 1601 possibly poisoned by his prosthetic, but nobody really nose for sure!
