SupernovaIn 1054, Chinese and other astronomers saw a supernova, a violently exploding star that was visible in daylight for 23 days and at night for almost 2 years. It is believed the Crab Nebula in the constellation Taurus is the remanant of this supernova. Rock paintings in North America suggest that Indians in Arizona and New Mexico saw it. There are no European records of the event. |
