Tycho Brahe observed it continuously for 16 months and published De Nova Stella, using parallax measurements to prove the star lay beyond the Moon's orbit, directly challenging Aristotle's doctrine that the heavens were eternal and unchanging. It became one of the triggers of the Scientific Revolution. Chinese records in the Veritable Records of the Ming and History of Ming's Treatise on Astronomy also describe it as "large as a cup, reddish-yellow with a faint blue-white tinge," visible until 1574.
