(3) November 6, 1572: Tycho Brahe recorded a "new star" in Cassiopeia. This dazzling Type Ia supernova was visible to the unaided eye – there were no telescopes then! – from early November 1572 into 1574.

However Halley was one of the greatest minds of his time and was known for his expert contributions to many fields of science. He also had a fun-loving side and was a jolly drinking companion to the future czar of Russia. You can read more about Halley's life: and more about Halley's Comet here:
