Tycho Brahe (born Scania, then part of Denmark but today part of Sweden, 1546; died Prague, then part of the Holy Roman Empire, October 24, 1601) was an astronomer and alchemist. The telescope had not yet been invented. However, he used the best instruments then available to make great contributions to the field of astronomy. He recorded planetary motions, observed a supernova, and mathematically concluded that comets were farther away from earth than the moon. He was not always correct in his work, but he provided the foundation for other great astronomers. Here is an interesting fact: in a duel (over an astronomical concept) he lost all or part of his nose. After the duel he wore a fake nose made out of metal.
