The first and the best known example is the Crab Pulsar.

The Crab Pulsar (PSR B0531+21) is a relatively young neutron star.

The 42 ft (12.8 m) dish is mainly used for observations of pulsars, and is normally continually monitoring the Crab Pulsar.

The Crab Nebula, and the Crab Pulsar within it, is an intensive space X-ray source.

In 1987 a millisecond pulsar was discovered in M4 with a period of 3.0 milliseconds or about ten times faster than the Crab Pulsar.

Baade's Star, now known as the Crab Pulsar, was first identified as being directly associated with the Crab Nebula by him.

Examples include the Crab Pulsar, the first pulsar to be discovered.

The Crab Pulsar itself was discovered in 1968.

The Crab Pulsar is believed to be about 28-30 km in diameter; it emits pulses of radiation every 33 milliseconds.
