A ROSAT X-ray image (false red color) superimposed on an optical image of a galaxy group. The image reveals hot gas confined by gravity, exceeding that of visible galaxies, indicating the presence of dark matter. This highlights the mystery surrounding dark matter's nature and abundance in the universe.

False-color X-ray image of the Centaurus Cluster's core, showcasing a massive, twisted plume of 10+ million degree gas spanning 70,000 light-years. Data from the Chandra X-ray Observatory reveals temperature variations (red-cool to blue-hot). The plume's mass is equivalent to a billion suns, possibly a wake from a moving central galaxy.
