A mysterious gamma ray signal found by NASA's fermi telescope was found in the nearby Andromeda Galaxy. Researchers then classify that the source of the rays might be dark matter. Find out more details here.
Another claim of dark matter has been rejected by XENON100's results. Dark matter has not yet been detected and still eludes detectors and researchers all around the world. Further experiments will possibly find the elusive type of matter, but until then, the universe is open to exploration.
The dark matter exists due to gravitational pull of galaxy clusters, and a new way to probe dark matter is by using atoms that have been stretched to be 4,000 times larger than usual.
