Puzzling X-rays Point to Dark Matter
ESA Space Science | 2014 Jun 24

Astronomers using ESA and NASA high-energy observatories have discovered a tantalising clue that hints at an elusive ingredient of our Universe: dark matter.

Although thought to be invisible, neither emitting nor absorbing light, dark matter can be detected through its gravitational influence on the movements and appearance of other objects in the Universe, such as stars or galaxies.

Based on this indirect evidence, astronomers believe that dark matter is the dominant type of matter in the Universe – yet it remains obscure.

Now a hint may have been found by studying galaxy clusters, the largest cosmic assemblies of matter bound together by gravity.
