This is a video by the two of the researchers who found anomalous xray emissions. These emissions may be
related to dark mater, needs further verification.

The significance of the detection depends, more than we'd wish, on dirty astrophysics involved in modeling the standard x-ray emission from galactic plasma.
The couch in the video looks a little like Dirac...mfb said:See also Update on the bananas
Dark matter is a type of matter that is hypothesized to make up a large portion of the universe. It does not interact with light and therefore cannot be directly observed, but its existence is inferred through its effects on visible matter.
Dark matter is thought to interact with ordinary matter gravitationally, causing the visible matter to heat up and emit X-rays. These X-rays can help scientists map the distribution of dark matter in the universe.
Dark matter is important because it makes up about 85% of the total matter in the universe, yet we know very little about it. Understanding dark matter could help us better understand the formation and evolution of galaxies and the large-scale structure of the universe.
Scientists use a variety of tools and techniques to study dark matter and its relationship to X-ray emissions. These include X-ray telescopes, computer simulations, and data analysis methods.
There are several theories about the nature of dark matter, including the possibility that it is made up of particles such as WIMPs (Weakly Interacting Massive Particles) or axions. Other theories propose modifications to our understanding of gravity, such as MOND (Modified Newtonian Dynamics), to explain the observed effects of dark matter.
