Spiral Galaxy NGC 4151 in Canes Venatici | Schulman Telescope

Spiral Galaxy NGC 4151 in Canes Venatici | Schulman Telescope

NGC 4151 is an intermediate spiral Seyfert galaxy with a weak inner ring structure. It is located around 52 million light-years from Earth in the constellation Canes Venatici. Seyfert galaxies have supermassive black holes at their centers that are surrounded by accretion discs of in-falling material. NGC 4151 has an active galactic nucleus (AGN)—a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum with characteristics indicating that the luminosity is not produced by stars. This galaxy was first mentioned by William Herschel on March 17, 1787.
