Stars with masses lower than 8 solar masses are thought to be too small to produce supernova explosions, and end their lives by producing a planetary nebula instead, while a star heavier than 12 solar masses would have produced a nebula with a different chemical composition to that observed in the Crab.
A significant problem in studies of the Crab Nebula is that the combined mass of the nebula and the pulsar add up to considerably less than the predicted mass of the progenitor star, and the question of where the ' missing mass ' is remains unresolved.

* 1054-July 4, Chinese astronomers noted the appearance of a guest star, the supernova now called the Crab Nebula, Messier's M1.
The Crab Nebula is a remnant of an exploded star.
In 1942, Jan Oort, convinced that the Crab Nebula was the " guest star " of 1054 described by the Chinese, asked sinologist J. J. L.
The location of the guest star can in principle be deducted from the statement “ to the south-east of Tianguan, perhaps several inches away “, which for a long time perplexed modern astronomers, because if Tianguan is almost universally regarded as a correspondent for the star Zeta Tauri ( ζ Tauri ), the Crab nebula, following a clearly old explosion of stars about 1000 years ago, and therefore a natural candidate for this guest star, is not situated in the south-east but to the north-west of this star ( see the General localisation of the Event section below ).
If we centre the research on the star ζ Tauri, there is a remnant located in the immediate proximity: the Crab Nebula.
