Originating 240 million light years away, the signal could be the best evidence yet of dark matter.

The concept of dark matter was devised as a way to account for the
missing mass in the universe that can be inferred to exist through
observations of the properties and motions of other astronomical bodies
but that cannot be directly detected.

Believed to make up 84.5%
of the matter in the universe, the nature of dark matter still remains
something of a mystery despite extensive efforts by scientists to prove
that it exists.

The newly detected signal, described as a “spike
of intensity at a very specific wavelength of x-ray light”, is thought
to come from the decay of a theoretical particle called a “sterile
neutrino” which interacts with normal matter through gravity.

If
this turns out to be correct then it could account for at least some of
the dark matter in the universe and in so doing help scientists to put
together one more piece of the puzzle in understanding the structure and
composition of the cosmos.
