| Notes: |
The Crab Nebula (Messier 1) is a supernova remnant in the constellation
Taurus. This nebula was the first astronomical object identified with a
historical supernova explosion. The supernova was recorded by Chinese
astronomers in 1054. The outer shells of the progenitor star were ejected and are still expanding with at a rate of about 1,500 kilometres per second nearly 1000 years after the explosion. At the center of the nebula lies the Crab Pulsar, a neutron star 30 kilometres across with a spin rate of 30 times per second, which emits pulses of radiation from gamma rays to radio waves. |
