Abstract
Why are space observatories important? The answer goes beyond twinkling stars in the night sky. Pockets of cold and hot air in Earth's atmosphere act as a hazy veil that many visible rays of light cannot penetrate. The atmosphere absorbs the majority of radiation from celestial bodies and distorts the types of light that do reach Earth's surface. Some types of radiation (like gamma rays) seldom reach Earth's surface. The radiation that Earth's atmosphere absorbs and distorts limits scientists' observations of stars, galaxies, and other celestial bodies. Even the most powerful ground based observatories can collect only a limited amount of data, but observatories in space collect data free from the distortion of Earth's atmosphere.
