non optical astronomy definition
Non-optical telescopes on the other hand observe radiation in the electromagnetic spectrum that isn't visible light: radio, microwave, infrared, ultraviolet, x-ray, and gamma. As IR radiation has a longer wavelength, the mirrors used in IR telescopes don’t need to be as perfectly shaped as those in visible telescopes. They observe things that give off or reflect light.

Non-optical astronomy is the study of the sky through forms of energy and particles that we cannot see with our unaided senses. Gamma rays come from all direction and can penetrate satellites into detector, so satellites need to be shielded or incorporate sensors to detect and account for rays coming in from other directions. ⢠On the basis of the visibility of the Electromagnetic radiation or anyparticle used to detect celestial objects Astronomy can be broadlydivided into two subdivisions.
