NGC 4151 is an active spiral galaxy about 50 million light years away in the constellation Canes Venatici. Its conspicuous, glowing core resembles the “Eye of Sauron” and points to a supermassive black hole. This Seyfert-1 galaxy is famous for its strong radiation and active galactic nucleus.
NGC 4156 is an elliptical galaxy about 80 million light years away, belonging to the environment of the Virgo Cluster. It shows a spherical structure and consists mainly of old, red stars, with little interstellar activity.
NGC 4145 is a smaller spiral galaxy, also about 50 million light years away, with a less pronounced structure and low activity at its centre. It is a typical example of a quieter, less conspicuous spiral galaxy.
