The predominant theory to explain the surprisingly low mass of this object is that some mass was carried away by stellar wind; however, that would have resulted in a shell around the object, and no such shell has been found.

This object has high concentrations of helium in a large band crossing its central region. The thickness of the atmosphere of Saturn's moon, Titan, was measured as it passed by the (*) synchrotron radiation emitted by an object that spins 30 cycles per second in the center of this nebula. This nebula with a pulsar at its center was first observed in 1731 by John Bevis. For 10 points, name this remnant of a supernova witnessed by astronomers in 1054, a nebula in the constellation Taurus which is designated M1.
