It's Friday. You need a pretty picture of space.

The latest offering from the Hubble should help carry you through to the weekend: Feast your eyes upon the majestic Crab Nebula.

Located 6,500 light-years away in the constellation Taurus (not Cancer, as one might expect — it gets its name from the crustacean-looking sketch astronomers first made of it) the Crab Nebula is the remnant of an ancient exploded star. Chinese astronomers recorded that supernova on July 4, 1054. The resulting nebula itself was discovered about 700 years later. Edwin Hubble connected the "new star" found by Chinese astronomers to this gorgeous celestial object in 1928.

At the heart of the Crab Nebula lies an incredibly dense neutron star — one with the same mass as our sun, but packed into a space the size of a small town, just a few miles across — left over from the star that exploded. It pulses like a beating heart, spinning 30 times a second and shooting out blistering pulses of radiation like clockwork. These rapidly spinning stars are known as pulsars, which are such accurate cosmic timekeepers that astronomers can use them to measure other phenomena. Interruptions in the pulses can be used to detect gravitational waves, for example.

"The neutron star is a showcase for extreme physical processes and unimaginable cosmic violence," a NASA statement reads.

The Crab pulsar is pictured in the center of the new image (it's the upper right star in that bright center pair). It's surrounded by the gaseous outer layers of the nebula, blasted into space when the dead star went supernova and left its dense core behind. The wispy trails forming an expanding ring around the star are moving at half the speed of light. The Crab Nebula is one of the most frequently imaged objects in our galaxy, but this is the first photo to showcase its violent, pulsing heart.
