About: List of X-ray space telescopes

An Entity of Type: artist discography, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

X-ray telescopes are designed to observe the x-ray region of the electromagnetic spectrum. X-rays from outer space cannot be observed from the ground due to absorption by the atmosphere, and so x-ray telescopes must be launched into orbit. Their mirrors require a very low angle of reflection (typically 10 arc-minutes to 2 degrees). These are called glancing (or grazing) incidence mirrors. In 1952, Hans Wolter outlined three ways a telescope could be built using only this kind of mirror.
