NGC 651 is a spiral galaxy located in the constellation of Cetus. It is approximately 30 million light-years away from Earth and is part of the Hubble Space Telescope observations. This galaxy is notable for its well-defined spiral structure and bright central region, which contains a high concentration of stars. Discovered by the astronomer John Herschel in 1834, NGC 651 is classified as a type Sc spiral galaxy. It is relatively small compared to other galaxies, with a diameter of about 50,000 light-years. Its study contributes to our understanding of galaxy formation and evolution in the universe.
