Glossary term: Atmospheric Extinction

Description: Atmospheric extinction is a phenomenon that occurs when part or all of the light from celestial objects is absorbed or reflected by the atmosphere. Atmospheric gases allow the entry of visible light and are transparent to radio and some infrared light, so these types of ground-based telescopes are widely used. To avoid this phenomenon and to observe other types of light, some telescopes are located beyond the atmosphere.
