A mysterious glow has been observed at the center of the Milky Way, and scientists are struggling to figure out exactly what’s causing it.
One possibility is that the high-energy X-rays that make up the baffling glow are “‘howls’ of dead stars as they feed on stellar companions.” At least that’s the way NASA’s Jet Propulsion Laboratory put it in a rather playful news release entitled “NASA’s NuStar Captures Possible ‘Screams from Zombie Stars.”
In more scientific terms, the glow may be evidence of dead stars in binary systems siphoning off material from their companions–a phenomenon that is known to release X-rays.
