(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. Although observed by a number of astronomers, Tycho's account was the most complete. It was one nail in the coffin of classical cosmology which maintained that the heavens were perfect and unchanging. And yet, here was a new star.

(1) Edmund Halley was born on November 8, 1656. His name is still known because of his analysis of the comet that bears his name. The comet was named for him when he correctly predicted its return. 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.
