High-energy astronomy is the study of astronomical objects that release electromagnetic radiation of highly energetic wavelengths.
It includes X-ray astronomy, gamma-ray astronomy, extreme UV astronomy, neutrino astronomy, and studies of cosmic rays.
The physical study of these phenomena is referred to as high-energy astrophysics.
[1] Astronomical objects commonly studied in this field may include black holes, neutron stars, active galactic nuclei, supernovae, kilonovae, supernova remnants, and gamma-ray bursts.
Some space and ground-based telescopes that have studied high energy astronomy include the following:[2] This astronomy-related article is a stub.
