This spiral galaxy in the constellation of Circinus is an example of a Seyfert galaxy, a class of active galaxy believed to be related to quasars, and which contain a super-massive black hole at their centre. The Circinus Galaxy is obscured from view by thick clouds of dust within the Milky Way, and was only discovered in 1975.
