Flashes of the Crab Pulsar

It somehow survived an explosion that would surely have destroyed our Sun.

Now it is spins 30 times a second and is famous for the its rapid flashes.

It is the Crab Pulsar, the rotating neutron star remnant of the supernova that created the Crab Nebula.

A careful eye can spot the pulsar flashes in the featured time-lapse video, just above the image center.

The video was created by adding together images taken only when the pulsar was flashing, as well as co-added images from other relative times.

The Crab Pulsar flashes may have been first noted by an unknown woman attending a public observing night at the University of Chicago in 1957 -- but who was not believed.

The progenitor supernova explosion was seen by many in the year 1054 AD.

The expanding Crab Nebula remains a picturesque expanding gas cloud that glows across the electromagnetic spectrum.

The pulsar is now thought to have survived the supernova explosion because it is composed of extremely-dense quantum-degenerate matter.
