EW YORK: According to new findings reported in the journal Nature, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted a mysterious glow of high-energy X-rays that scientists say could be the “howls” of dead stars as they feed on their stellar companions. These howls, it seems, are coming from the very center of our galaxy, where everything from young stars, to small black holes, to moats of dust, all swarm around the supermassive black hole known as Sagittarius A.
“Almost anything that can emit X-rays is in the galactic center,” Kerstin Perez of Columbia University in New York, the lead author of the study, explained in a statement. “The area is crowded with low-energy X-ray sources, but their emission is very faint when you examine it at the energies that NuSTAR observes, so the new signal stands out.”
