Publishing in the journal Nature, astronomers say such visible evidence provides observational data comparably reliable to that gathered via X-rays.
Lead author Mariko Kimura, notes, "We now know that we can make observations based on optical rays -- visible light, in other words -- and that black holes can be observed without high-spec X-ray or gamma-ray telescopes."
A summary of the findings explains, "Once in several decades, some black hole binaries undergo "outbursts", in which enormous amounts of energy -- including X-rays
