Benchmarks: July 4, 1054: "Birth" of the Crab Nebula

On July 4, 1054, Chinese and Japanese astronomers observed a new, iridescent yellow point of light in the constellation Taurus. This “guest star,” said to be as bright as the moon, failed to disappear with the rising sun — for a month, it shone both night and day. Even after fading during daytime, it remained in the night sky for nearly two years, by some accounts. Historians and scientists think that this event was likely the supernova that created the Crab Nebula, one of the most spectacular and rare astronomical features in the known universe.
