Circinus Galaxy

March 31, 2003
Atlas Image mosaic, covering 8.3´ × 17.1´ on the sky, of the Circinus Galaxy. This spiral galaxy, in the constellation Circinus, is relatively nearby, at only 4 Mpc (13 million light years), and is seen through a window of low extinction (only about 1.5 visual magnitudes) near the Galactic Plane. Observations in the optical, X-rays, and radio indicate that Circinus has a Seyfert 2 nucleus, that is, the galaxy is harboring a supermassive black hole at its center. 2000 June 14-20
