Did you mean a Pulsar?

• Florin_Andrei 6y ago
  They're all neutron stars. Magnetars are young and make some of the strongest magnetic fields in the universe. Pulsars are old and weak, and make regular beeps if you're watching them from the right place. They're probably on a spectrum, as opposed to rigidly separated categories. There's a hypothesis that the fast radio bursts like the ones detected here might be produced by magnetars.
