While walking home on November 11, 1572, astronomer Tycho Brahe idly glanced at the sky. He was surprised to see a bright star in the constellation Cassiopeia that hadn`t been there before. The new star, which we now know to be the result of a stellar explosion or supernova, grew brighter than Venus and was visible in daylight for about two weeks. It then slowly faded until vanishing in March 1574, 16 months after its discovery.
