Question

Quizplus · Accepted Answer

The formation of the Solar System and the existence of AGNs both involve the existence and importance of accretion disks. In the formation of the Solar System, an accretion disk of gas and dust formed around the young Sun, eventually leading to the formation of planets. In AGNs, an accretion disk of gas and dust forms around the supermassive black hole at the center of a galaxy, fueling the release of massive amounts of energy.
