Years after a supernova flash, astronomers noticed a growing radio signal. By combining several telescopes into a giant antenna, they spotted a tiny, almost stationary source. Everything points to a young pulsar — a spinning neutron star that, like a lighthouse, beams narrow jets of radiation. If co

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.
