much credit while he was alive‚ but his idea started to catch on. Tycho Brahe 1546-1601 Tycho was friends with the king of Denmark‚ consequently the king gave Tycho a big observatory‚ which Tycho used to make precise measurements of the stars and planets. Tycho was the first to realize that the sky did change and evolve.
