A pulsar is an astronomical object that emits radiation in the form of rapid pulses. One such object that does this is a rotating neutron star. Think of it similar to a lighthouse beacon in space.
When the first pulsar was discovered, it did cross the minds of astronomers that they were possibly seeing a transmission from alien life. However, upon discovery of more pulsars that hypothesis was entirely abandoned.
