M1 – The Crab Nebula (HOO)

The Crab Nebula – HOO Palette

M1, the Crab Nebula, is the result of a star that exploded in 1054 AD. It was recorded by astronomers in China as a “guest star” in the constellation Taurus. The supernova explosion was visible during the day for three weeks and was visible to the naked eye at night for two years before fading from view. A pulsar rotating 30 times per second was formed as a result of the supernova. The remnant nebula is about 10 light years across and still expanding, with changes to its structure visible over the course of days. It lies about 6,500 light years from Earth. In 1928, Edwin Hubble proposed that the nebula was associated with the “guest star” from 1054 AD. This was later proved by Nicholas Mayall.
