High energy astronomy is the study of astronomical objects that release EM radiation of highly energetic wavelengths. It includes X-ray astronomy, gamma-ray astronomy, and extreme UV astronomy, as well as studies of neutrinos and cosmic rays. The physical study of these phenomena is referred to as high-energy astrophysics.

Astronomical objects commonly studied in this field may include black holes, neutron stars, active galactic nuclei, supernova remnants, Gamma ray bursts, and quasars.
