Accretion disks are rotating structures of gas, dust, and other material that form around massive celestial objects, such as black holes, neutron stars, or young stars, due to gravitational attraction. These disks play a crucial role in the growth of the central object and emit significant electromagnetic radiation, often observed in X-ray and visible wavelengths, as material spirals inward and heats up due to friction and other processes.

Black holes are regions in space where the gravitational pull is so strong that nothing, not even light, can escape from them. They are formed when massive stars collapse under their own gravity at the end of their life cycles, leading to singularities surrounded by an event horizon.

Neutron stars are the remnants of massive stars that have undergone supernova explosions, resulting in an incredibly dense object primarily composed of neutrons. They exhibit extreme gravitational and magnetic fields, and their study provides insights into fundamental physics and the behavior of matter under extreme conditions.

Gravitational attraction is the force by which every mass in the universe pulls on every other mass, with the strength of the force being directly proportional to the product of the masses and inversely proportional to the square of the distance between their centers. This fundamental interaction is responsible for the formation of planets, stars, galaxies, and the overall structure of the universe.

Electromagnetic radiation is a form of energy that travels through space at the speed of light, encompassing a wide range of wavelengths and frequencies known as the electromagnetic spectrum. It includes visible light, radio waves, X-rays, and more, each with unique properties and applications in fields like communication, medicine, and astronomy.
