Discovered by William Herschel in 1790, NGC 1097 is an interesting combination of features. First, it is tidally interacting with its companion, NGC 1097A, see in the upper side of the galaxy, to the right, causing distortions in the spiral arms.

NGC 1097 is also a Seyfert galaxy, with four optical jets projecting from the core. However, these appear to not be from an active galactic core, but are the full of stars and seem to be the remains of a cannibalized dwarf galaxy.

The bright ring near the center is a star-forming region around the central black hole, a region about 5000ly in diameter created by infalling gas and dust, while the arms are tens of thousands of light years wider.
