A black hole that's gobbling down a stellar meal is providing insight into how black holes devour matter and affect the evolution of galaxies. Researchers found that the X-ray signal burst caused when a black hole shredded a passing star was repeated in the radio wavelengths nearly two weeks later. The radio echo most likely came from an exodus of highly energetic particles streaming out of the black hole, the researchers said. In , Las Cumbres Observatory's All-sky Automated Survey for Supernovae, a collection of robotic telescopes spread across the globe, picked up signals from million light-years away.
