Third pole theory for nebula.
They think the nebula, first recorded by Chinese astronomers in 1054, may be the first cosmological object with a third magnetic pole.
The Crab Nebula, in the constellation Taurus, is a pulsar - a source of powerful radiation shooting in pulses from a spinning object at its centre, like a lighthouse beam. The radiation emissions from the north and south poles of a pulsar should be identical. But observations from the Arecibo radio telescope in Puerto Rico show those from the Crab Nebula are not.
