Astronomers have detected a mysterious signal 240 million light years away from Earth, in the Perseus Cluster (top), one of the most massive objects in the Universe. The unidentified signal is a "spike of intensity at a very specific wavelength of X-ray light." Scientists don't know yet what is the origin.
One of their theories is really interesting: It may be "produced by the decay of sterile neutrinos, a type of particle that has been proposed as a candidate for dark matter." According to Esra Bulbul, at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts:
''We know that the dark matter explanation is a long shot, but the pay-off would be huge if we're right. So we're going to keep testing this interpretation and see where it takes us.''
