The Circinus Galaxy (ESO 97-G13) is a Seyfert Galaxy [2] in the Circinus constellation. It is only 4 degrees below the Galactic plane, and 13 million light-years away. The galaxy is undergoing tumultuous changes, as rings of gas are being ejected from the galaxy. The outermost ring is 700 light-years from the center of the galaxy and the inner ring is 130 light-years out. The Circinus galaxy can be seen using a small telescope, however it was not noticed until 25 years ago because it was obscured by material from our own galaxy. The Circinus Galaxy is a Type II Seyfert galaxy and closest known active galaxy to the Milky Way.
