With money from the King of Denmark he built a large [[observatory]] called [[Uraniborg]] on the island of [[Hven]] in [[Denmark]]. He discovered that the [[universe]] outside the [[Solar System]] could change when he studied [[SN 1572|a supernova]] and a [[comet]]. [[Johannes Kepler]] was his assistant. Tycho made very careful observations of the planets. When Tycho died in 1601, Kepler continued Tycho's work. Tycho was not a modern scientist. He believed in [[astrology]], and his astronomy was a strange mixture of scientific observation and religious belief. Although he rejected the [[Claudius Ptolemaeus|Ptolemaic]] system, he also rejected the [[Copernicus|Copernican]] system.<ref>Blair, Ann 1990. Tycho Brahe's critique of Copernicus and the Copernican s
