Glossary term: X-Ray Telescope

Description: An x-ray telescope is a type of telescope specially designed to capture high-energy, high-frequency, x-ray light that is invisible to the human eye. Since the atmosphere absorbs a large amount of these x-rays, these telescopes must be located in space. The high frequencies of x-rays makes them difficult to focus so the optics of these telescopes are complex.
