1538Christopher Clavius was a Jesuit German astronomer. At the time he was probably the most respected astronomer in Europe and his textbooks were used for astronomical education for over fifty years. He located (independently of Tycho Brahe) the nova from 1572 in the fixed stars sphere (in the constellation of Cassiopeia) and found that the position of the nova was exactly the same for all observers. That meant that it had to be beyond the Moon, and the doctrine that the heavens could not change was proven false. A large crater on the Moon was named in his honor.
