Experts say object is a match for predicted class of neutron star with ultra-powerful magnetic field
Astronomers have discovered a mysterious object emitting a radio wave beam that pulsed every 20 minutes.
The team behind the discovery believe the object could be a new class of slowly rotating neutron star with an ultra-powerful magnetic field. The repeating signals were detected during the first three months of 2018, but then disappeared again, suggesting they were linked to a dramatic, one-off event, such as a starquake.
