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.

Eartha Kitt's death was announced today. I think that's a very sad thing. I recommend staying with the video all the way through "Old Fashioned Girl" to hear "Santa Baby" sung by the first, and the best, interpreter of that song. Not to mention the little poke she takes at Madonna's ill-considered attempt at the tune.
