Arp77 consists of the larger barred spiral galaxy NGC 1097 and its smaller companion, the elliptical galaxy NGC 1097A. Located approximately 45 million light-years away in the constellation Fornax, these galaxies are engaged in a gravitational interaction that has visibly distorted their structures. NGC 1097, classified as a Seyfert galaxy, hosts an active galactic nucleus powered by a supermassive black hole, while the interaction with NGC 1097A has sparked intense starburst activity and created a striking ring of star formation around its core.
