On this day in 1968 - February 24th - the discovery of the first pulsar was announced.

A pulsar is a fast-rotating neutron star that emits a beam of electromagnetic radiation. We can only detect it when it's pointing towards us, rather like a lighthouse, so it seems to pulse. A neutron star is the remnant of a massive star following the collapse of its core in a supernova explosion.
