NGC 1097 – Caldwell 67

Click here for full resolution image

NGC 1097 is a 9.5×6.5 arcmin barred spiral galaxy, seen face-on. This galaxy is about 45 million light years away and located in the constellation Fornax.

NGC 1097 is a Seyfert 1 galaxy. Seyfert galaxies have a bright, active nucleus (fed by a supermassive black hole). They then look like a normal galaxy with a “star” superimposed at its center. It is thus, not easy to grab enough detail from the central zone. In the picture, and in the attached, highly stretched, negative image, it is easy to see the presence of three of the four theoretical jets that irradiate from the galaxy. These jets are supposed to be star streams originated in a collision with a smaller galaxy.
