Properties of Supernovae
... Supernovae are rare events, occurring only once or twice per century in a typical galaxy. There have been just six supernovae seen in the Milky Way in recorded history, with the most recent occurring in 1604, just before the advent of telescopes. The perceptive reader will notice that this rate is m ...
