NGC 7797

NGC 7797 is a spiral galaxy located approximately 85 million light-years away in the constellation Pisces. It is classified as a SA(s)c type galaxy, indicating it is a spiral galaxy with loosely wound arms and a small bulge in its center. The "SA" classification signifies that it is a typical spiral galaxy, lacking a bar-shaped structure. The "(s)" notation further specifies that the spiral arms originate directly from the nucleus, rather than from a ring around it.

NGC 7797 is known for its numerous HII regions, which are areas of ionized hydrogen gas where active star formation is occurring. These regions appear as bright knots or patches along the spiral arms.

It is considered a relatively isolated galaxy, meaning it does not have any major galaxy neighbors that are significantly gravitationally interacting with it. This isolation can affect its evolution, potentially influencing its star formation rate and overall morphology.

NGC 7797 is studied by astronomers to understand the formation and evolution of spiral galaxies, particularly those with loosely wound arms and high rates of star formation. Its distance makes it a good target for studying stellar populations and the distribution of dust and gas within a spiral galaxy.
