The Crab Pulsar Wind Nebula (also known as a plerion, or synchrotron nebula.) At the heart of the Crab Nebula lies a pulsar, a spinning, stellar scale object with the density of a neutron, left over as the result of a supernova, in particular one caused by the collapse of a massive star. This Chandra X-ray image clearly shows some of the structure surrounding the Crab's pulsar. As usual, this is an APOD image. The picture here links to APOD page, and a click there will show a higher res view.
