List of space telescopes : ウィキペディア英語版 | List of space telescopes
This list of space telescopes (astronomical space observatories) is grouped by major frequency ranges: gamma ray, x-ray, ultraviolet, visible, infrared, microwave and radio. Telescopes that work in multiple frequency bands are included in all of the appropriate sections. Space telescopes that collect particles, such as cosmic ray nuclei and/or electrons, as well as instruments that aim to detect gravitational waves, are also listed. Missions that look solely within our solar system, including the Earth, Sun, and other planets within our system, are mostly excluded; see List of Solar System probes for these. Two values are provided for the dimensions of the initial orbit. For telescopes in Earth orbit, the min and max altitude are given in kilometers. For telescopes in solar orbit, the minimum distance (periapsis) and the maximum distance (apoapsis) between the telescope and the center of mass of the sun are given in astronomical units (AU). == Gamma ray ==
Gamma ray telescopes collect and measure individual, high energy gamma rays from astrophysical sources. These are absorbed by the atmosphere, requiring that observations are done by high-altitude balloons or space missions. Gamma rays can be generated by supernovae, neutron stars, pulsars and black holes. Gamma ray bursts, with extremely high energies, have also been detected but have yet to be identified.〔(【引用サイトリンク】 title=Gamma rays )〕
