X-ray Telescope
An X-ray telescope is a type of telescope that is designed to observe high-energy electromagnetic radiation in the X-ray spectrum. Unlike optical telescopes, X-ray telescopes do not use lenses or mirrors to focus the radiation. Instead, they use grazing incidence mirrors that reflect the X-rays at very shallow angles, allowing them to be focused onto a detector. X-ray telescopes are used to study a wide range of astrophysical phenomena, including black holes, neutron stars, supernovae, and active galactic nuclei.
