X-ray, Optical & Radio Images of VLA J2130+12
By combining data from Chandra and several other telescopes, astronomers have identified the true nature of an unusual source in the Milky Way galaxy. This discovery implies that there could be a much larger number of black holes in the Galaxy that have previously been unaccounted for. The images on the left show X-rays from Chandra and an optical image from Hubble of a large area around the source VLA J2130+12, including M15. The images on the right show the source VLA J2130+12 that is bright in radio waves, but can only be giving off a very small amount of X-rays. These pieces of information indicate the source contains a black hole with a few times the mass of the Sun.
