NGC 7318 is a pair of interacting galaxies located in the constellation Pegasus. It is part of the Stephan's Quintet, a group of five galaxies that are known for their gravitational interactions. NGC 7318 consists of two galaxies, NGC 7318A and NGC 7318B, which are in the process of colliding and merging. These galaxies are approximately 300 million light-years away from Earth. The interaction between NGC 7318A and NGC 7318B has led to the formation of new stars and the distortion of their shapes. This dynamic event provides valuable insights into the processes of galaxy evolution and the effects of gravitational forces in the universe.
