Supermassive black holes are among the the most thrilling and puzzling objects in the universe. These are the huge, massive bodies that sit at the coronary heart of most, probably all, galaxies. Indeed, they could be the seeds from which all galaxies improve.
Supermassive black holes are at minimum a hundred thousand times the mass of our solar. They are generally surrounded by thick clouds of gasoline that radiate vast amounts of energy. When this takes place, they are termed active galactic nuclei. Exploring the homes of these clouds, and their curious central inhabitants, is an ongoing training for astrophysicists.
