What exactly did Tycho Brahe do?
He was the first Western astronomer to describe a Nova in 1572 he observed a new bright star in the constellation of Cassiopeia In 1573 he published a small book, De nova stella coining the term nova for a “new” star. His astronomical observations are considered an essential contribution to the Scientific Revolution. A traditional view of Tycho, originating in the 1654 biography Tychonis Brahe, equitis Dani, astronomorum coryphaei, vita by Pierre Gassendi and furthered by the 1890 biography by Johann Dreyer, which for a long time was considered the most essential work on Tycho, is that Tycho was primarily an empiricist, who set new standards for precise and objective measurements for astronomical and planetary observations. Which Kepler would later use Tycho’s astronomical information to develop his own theories of astronomy.
