Here’s the Chandra X-Ray telescope view of the Perseus Galaxy Cluster from 2003:

The Chandra image shows the supermassive black hole at the center of Perseus A, seen as a white point. This image is 350 thousand light years across at the distance of the Perseus cluster. The hot cluster gas is seen as diffuse emission, and two cavities in the cluster gas are visible on either side of the black hole. Low-energy X-rays (0.3-1.5 keV) are shown in red, medium-energy X-rays are shown in green (1.5-3.5 keV), and high-energy X-rays are shown in blue (3.5-7.0 keV).
It may not be so cool as others, but it has a certain faux-retro feel to it in the graininess, as well as a slightly 3-D impression. Cool stuff.
