Discovery

Modern observations by Carl Otto Lampland uncovered that Crab Nebula is changing in its structure. This discovery led to conclusion that Carb Nebula formed from bright star recorded by Chinese astronomers is AD 1054, which turned out to be Supernova that is responsible for creation of Crab Nebula. This nebula was identified as supernova remnant 1921-1942 (speculations in 1920s, plausibility in 1939 and beyond reasonable doubt 1942 by Jan Oort).

 

Formation

SN 1054 was a supernova observed on 4 July 1054, and vas visible for two years. This supernova formed pulsar now called Crab Pulsar.
