Above the Southern Horn of Taurus.

The article focuses on Crab Nebula, a supernova remnant in the Taurus constellation. It highlights the different sketches of the Crab Nebula from various astronomers including Lord Rosse and Wilhelm Tempel. Also emphasized are the discovery of the radio emission of the Crab Nebula, its relation to the 1054 Chinese guest star and the proposal of Edwin Hubble that its expansion rate and location support the conceptualization that it is indeed a remnant of the 1054 supernova.
