Now I'm confused senseless as to which source is correct. Oh well. I had a look to see if I could find the info where my knowledge is based on, but only could come up with what I've quoted below. It's the same info, but the one I read had more details regarding the discovery. I seem to recall a woman first coming across it, then others got into it. In trying to find this info I came across something I didn't know- that William Herschell discovered Uranus. Wow!

"Pulsars are sources of powerful electromagnetic radiation, emitted in short and extremely regular pulses many times a second. They were a great mystery when discovered in 1967, and the team which identified the first one considered the possibility that it could be a signal from an advanced civilization.[24] However, the discovery of a pulsating radio source in the centre of the Crab Nebula was strong evidence that pulsars were formed by supernova explosions. They are now understood to be rapidly rotating neutron stars, whose powerful magnetic field concentrates their radiation emissions into narrow beams."
