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]
The Crab Nebula was identified as the supernova remnant of SN 1054 between 1921 and 1942, at first speculatively (1920s), with some plausibility by 1939, and beyond reasonable doubt by Jan Oort in 1942. In 1921, Carl Otto Lampland was the first to announce that he had seen changes in the structure of the Crab Nebula. [4]
In 1731, Bevis had been the first to notice what we now call the Crab Nebula (Messier 1). Uranographia Britannica was the first of the "classical" star atlases to include non-stellar objects. In 1750, as the atlas was still in the process of being compiled, Bevis's publisher, John Neale was declared bankrupt, the copper plates sequestered by ...
Other astronomers, using side notes in Messier's texts, eventually filled out the list up to 110 objects. [9] The catalogue consists of a diverse range of astronomical objects, from star clusters and nebulae to galaxies. For example, Messier 1 is a supernova remnant, known as the Crab Nebula, and the great spiral Andromeda Galaxy is M31.
Astronomers picked out wispy never-before-seen features of the Crab Nebula, the remnant of an exploded star, using the James Webb Space Telescope.
In the northeast part of Taurus is Messier 1, more commonly known as the Crab Nebula, a supernova remnant containing a pulsar. One of the closest regions of active star formation, the Taurus-Auriga complex, crosses into the northern part of the constellation. The variable star T Tauri is the prototype of a class of pre-main-sequence stars.
It spins at a rate of 30 times per second, spewing energy beams and taking on a decidedly pulsating appearance.
