The Dark Matter theory was first formulated over 7 decades ago, but latest discovery by science experts showed the first indication of the mysterious invisible astronomical mass.  According to the study, researchers have picked up astonishing signals coming from the Perseus galaxy constellation and in the Andromeda galaxy.

Science experts have allegedly discovered a Dark Matter signal. According to Space.com, a team of astronomers spotted an unusual spike in X-ray emissions coming from two different celestial objects, which are the Andromeda galaxy and the Perseus galaxy cluster while pondering over the information collected by the European Space Agency's XMM-Newton spacecraft.

Based on its encyclopedic definition, Dark Matter is a kind of astronomical and cosmological matter accounted for gravitational effects, which appear to be the result of an invisible mass. Evidently, it cannot be seen telescopically and it neither emits nor absorbs light or other electromagnetic radiation at any significant level.

The Dark Matter discovery is hypothesized by science to simply be matter that is non-reactant to light. Instead, its existence and properties of dark matter are inferred from its gravitational effects on visible mass, radiation and the large-scale structure of the universe.

In science, all atoms emit a unique pattern of light called a spectrum that helps astrophysicists to determine what planet and stars are made from at great distances. However, The Huffington Post said the Dark Matter discovery showed a spectrum from the Perseus constellation and Andromeda have spikes where nothing should exist.

Switzerland's École Polytechnique Fédérale de Lausanne (EPFL) Laboratory of Particle Physics and Cosmology (LPPC) and The Netherlands' Leiden University science experts believed the latest discovery is the result of particles of Dark Matter decaying and shooting out particles of light called as photons.

The scientists also said the dispersal of the signals within the galaxy resembles to where the largest concentrations of Dark Matter should supposedly exist.

"We think what we have discovered is the decay of a particle of Dark Matter," the EPFL's LPPC study coauthor Dr. Oleg Ruchayskiy stated. "It could usher in a new era in astronomy."

EPFL and The Netherlands' Leiden University lead author Alexey Boyarsky also commented on the Dark Matter discovery by several science experts.

"Dark matter is everywhere, though it's very hard to catch. Everybody is looking for it and this may be the first sign," Boyarsky said. "Confirmation of this discovery may lead to construction of new telescopes specially designed for studying the signals from dark matter particles. We will know where to look in order to trace dark structures in space and will be able to reconstruct how the universe has formed."

The latest Dark Matter discovery by science experts could usher a new astronomical era. The results of the research will be published in the journal, Physics Review Letters, next week.
