Astronomers observed the radio burst for three years and noticed that the cloud of scattering particles around it was thinning — a sign of an expanding supernova. A temporary intensification of the magnetic field pointed to a neutron star with an extraordinarily powerful field.

The spiral radio jet of the 'Corkscrew Galaxy' served as a natural magnetometer: astronomers compared its bends with Faraday rotation measure and proved that RM oscillations are synchronous with its morphology. In the eastern part of the jet, rotation is generated by its own magnetic field, while in
