The frustrating quest for dark-matter continues. An unidentified X-ray signature recently observed in a nearby galaxy clusters is not due to the decay of dark matter, researchers report. The findings ruled out previously proposed interpretations of dark matter particle physics. But the near future for solving this great mystery of 21st-century astronomy looks bright.

Our massive Milky Way Galaxy –the second-largest galaxy in the Local Group after the Andromeda Galaxy–is orbited by more than twenty dwarf galaxies that are thought to be relics of the very first galaxies in the universe, A new ultra-faint dwarf galaxy (UFD), the least luminous, most dark matter dominated, and least chemically evolved galaxies known, has been discovered at a distance of about 293,000 light years away from the Earth.
Scientists working at the frontier of particle physics are proposing the existence of a theoretical exotic, ultra-light boson with a mass billions of times smaller than that of the electron. They are seeking a ‘darker’ origin of the ripples in spacetime, at the same time proving the existence of a dark-matter particle. Theories about the origin of dark matter in the universe –one of the biggest questions in science–vary from suggesting that it may be older than the Big Bang to the existence of particles the size of galaxies.
Such a phase transition would be a dramatic event, even for something as spectacular as the universe.
