From Astronomy Picture of the Day:
This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The above image, taken by the Hubble Space Telescope, is presented in three colors chosen for scientific interest. The Crab Nebula spans about 10 light-years. In the nebula’s very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.

Damn, that’s gorgeous!
However, I’m fond of these images. Also stunning. Plus I know several of the folks who work/have worked on the Spitzer program.
Ooo, that’s just lovely. Here’s a closer look at the center of the Crab Nebula, with data from the Chandra X-Ray Observatory. And movies! You can imagine the hell of radiation and electromagnetic forces that must exist around that pulsar.
More things in heaven and earth…
That’s spectacular. The infinite variety, beauty, power and mystery of the universe never fails to move me.
