ABOUT THIS IMAGE: Portrayed in this image is the spiral galaxy NGC 4945, a close neighbor of the Milky Way. Belonging to the Centaurus A group of galaxies, it is located at a distance of almost 13 million light-years. Showing a remarkable resemblance to our own galaxy, NGC 4945 also hides a supermassive black hole behind the thick, ring-shaped structure of dust visible in the picture. But, unlike the black hole at the center of our Milky Way, the million-solar-mass black hole inside NGC 4945 is an Active Galactic Nucleus that is frantically consuming any surrounding matter, and so releasing tremendous amounts of energy. This
image combines observations performed through three different filters
(B, V, R) with the 1.5-metre Danish telescope at the ESO La Silla Observatory
in Chile. |
