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.

The Crab Nebula is a remnant of an exploded star. This is the Crab Nebula in various energy bands, including a hard X-ray image from the HEFT data taken during its 2005 observation run. Each image is 6' wide. The guest star reported by Chinese astronomers in 1054 is identified as SN 1054. The highlighted passages refer to the supernova.
The Southern Crab was noted in a 1967 catalog, and was also observed using a CCD imager with the 2.2 meter telescope at the La Sila observatory in 1989. [4] The 1989 observation marked a major expansion of knowledge about the nebula, and it was observed using various filters.
Astronomers picked out wispy never-before-seen features of the Crab Nebula, the remnant of an exploded star, using the James Webb Space Telescope.
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 ...
Rosse's telescope Leviathan was the first to reveal the spiral structure of M51, a galaxy nicknamed later as the "Whirlpool Galaxy", and his drawings of it closely resemble modern photographs. The Crab Nebula received its name based on a drawing made by Rosse in the early 1840s with his older 36-inch (91 cm) telescope in which it resembled a ...
