The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons, 3rd Earl of Rosse , in 1842 or 1843 using a 36-inch (91 cm) telescope . [ 6 ]
In 1928, Edwin Hubble was the first to note that the changing aspect of the Crab Nebula, which was growing bigger in size, suggests that it is the remains of a stellar explosion. He realised that the apparent speed of change in its size signifies that the explosion which it comes from occurred only nine centuries ago (as observed on Earth ...
Edwin Powell Hubble (November 20, 1889 – September 28, 1953) [1] was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology .
It spins at a rate of 30 times per second, spewing energy beams and taking on a decidedly pulsating appearance.
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova. The known history of supernova observation goes back to 1006 AD. All earlier proposals for supernova observations are speculations with many alternatives. Since the development of the telescope, the field of supernova discovery has expanded to other galaxies. These ...
Edwin Hubble discovered that the universe is expanding and that the farther away a galaxy is, ... the Crab Nebula, and the galaxies Centaurus A and M87. 1938

For example, Messier 1 is a supernova remnant, known as the Crab Nebula, and the great spiral Andromeda Galaxy is M31. Further inclusions followed; the first addition came from Nicolas Camille Flammarion in 1921, who added Messier 104 after finding Messier's side note in his 1781 edition exemplar of the catalogue.
