NGC 4151

NGC 4151 is a bright galaxy located about 60 million light-years away, known for its active supermassive black hole at its center. This black hole pulls in surrounding gas and dust, creating a highly energetic region called an active galactic nucleus (AGN). As material spirals inward, it emits intense radiation across the electromagnetic spectrum, making NGC 4151 one of the most studied Seyfert galaxies. Its brightness variations help scientists understand black hole behavior and galaxy evolution. Overall, NGC 4151 offers valuable insights into how supermassive black holes influence their host galaxies.
