NGC 1097 is a barred spiral galaxy about 45 million light-years away in the constellation Fornax. Three supernovae (SN 1992bd, SN 1999eu, & SN 2003B) have been observed in NGC 1097 (as of 2006).
NGC 1097 is also a Seyfert galaxy, with jets shooting from the core. Like most galaxies, NGC 1097 has a supermassive black hole at its center. Around the central black hole is a ring of star-forming regions with a network of gas and dust that spirals from the ring to the black hole.
NGC 1097 has two satellite galaxies. NGC 1097A is the largest of the two. It is a peculiar elliptical galaxy that orbits 42,000 light-years from the center of NGC 1097. NGC 1097B is the outermost one and not much is known about that.
