Contrast that with an example of a neutron star (aka pulsar) – a mere 12.5 miles in diameter – that rotates once every 1.4 milliseconds, or 42,960 times every minute!

Typically pulsars emit electromagnetic radiation in beams that emanate from their magnetic poles, much like a coastal lighthouse has s weeping rotting beam.

To0 detect a pulsar, its beam has to be pointed in our direction and we have to have equipment capable of detecting what look like incredibly quick pulses of radio waves.

The Milky Way’s YOUNGEST pulsar, Kes 75, is a mere 500 years old, 19,000 light years away and its expanding nebula has wind fronts racing away at 2 million miles/hour.
