tycho

Tycho Brahe (1546–1601) was a Danish nobleman and a leading figure in astronomy before the telescope era. He collected and documented precise astronomical observations, including positions of planets and comets, contributing to the eventual development of Kepler's laws. He built the observatories Uraniborg and Stjerneborg, and developed large precision instruments and meticulous data records. His work laid the groundwork for later scientists, and his measurements and star catalogs aided Johannes Kepler in formulating the laws of planetary motion. He also proposed the Tychonic system, a geoheliocentric model in which Earth remains at the center while the Sun and Moon orbit Earth and the other planets orbit the Sun.

Tycho, the musician, is the stage name of Scott Hansen, an American ambient and downtempo musician and designer. Emerging in the early 2000s, Tycho released material on Ghostly International and rose to prominence with a lush, instrumental sound that blends analog synth textures with soft percussion. Albums such as Dive (2011), Awake (2014), and Weather (2019) have helped define contemporary ambient music. The project name honors Tycho Brahe.

Tycho is also a prominent lunar impact crater named after Tycho Brahe. Located in the Moon's southern highlands, Tycho features a bright appearance with a prominent ray system visible during full Moon phases, a central peak, and a diameter of about 85 kilometers. It is a widely observed feature used in selenographic studies and as a reference point for lunar navigation.
