NASA’s Chandra satellite detects distinct X-ray signal, may prove existence of dark matter


A little yet particular X-beam flag distinguished from the Milky Way world by NASA's Chandra satellite may help demonstrate the presence of dull matter, researchers have asserted. 

Specialists, including those from Massachusetts Institute of Technology (MIT) and Yale Center for Astronomy and Astrophysics in the US, dissected the vitality range of X-rays.They discovered more X-beam photons with a specific vitality than would be normal on the off chance that they were delivered just by well known procedures. 

Those photons could in actuality have been produced by the rot of dull matter particles, say the specialists. This is not the first occasion when that researchers have seen additional photons with a vitality of around 3,500 electronvolts in the spectra recorded by X-beam satellites. 

Be that as it may, beforehand it was uncertain whether the knock, or line, made by the photons in the generally smooth range was only an instrumental antique, said Kevork Abazajian, from the University of California, Irvine. Researchers figure that dull matter makes up more than 80 for every penny of all the mass in the universe. 

As its name recommends, it radiates no light, however uncovers its nearness through the gravitational pull it applies on stars inside worlds. For a considerable length of time, physicists have been attempting to distinguish particles of dim matter specifically by blocking them utilizing instruments on Earth. The most recent research, did by Nico Cappelluti at Yale, targets generally light particles of dim matter, 'BBC News' accounted for. 

Esra Bulbul of the Kavli Institute for Astrophysics and Space Research at the MIT was the principal researcher to detect an atypical line at 3.5 keV, when taking a gander at the X-beam spectra of huge quantities of world groups in 2014.
