Give+an+account+of+AGN

AGN stands for Active Galactic Nuclei. This galaxies are among the oldest and most luminous galaxies in the universe. Like all galaxies they have super massive blackholes in the center. These galaxies are study because of all of these reasons. Since AGN are so bright it is easier for us to observe them from Earth. Even far away galaxies can be since they are so bright. AGN are some of the eldest galaxies in the universe, making them interesting to observe. Studying AGN we can make theories about what will happen to our galaxy and figure out the evolutions of galaxies. AGN are also interesting as they have super massive blackholes, and scientists believe one day we can maybe observe them in the middle of an AGN.
