#OTD in 1054.

Chinese astronomers recorded the sudden appearance of a "guest star", later identified as the supernova that created the Crab Nebula (SN 1054).

Modern understanding that the Crab Nebula was created by a supernova traces back to 1921, when Carl Otto Lampland announced he had seen changes in the nebula's structure.
