electromagnetic radiation of highly
energetic wavelengths. It includes
X-ray astronomy,
gamma-ray astronomy
Gamma-ray astronomy is the astronomical observation of gamma rays,Astronomical literature generally hyphenates "gamma-ray" when used as an adjective, but uses "gamma ray" without a hyphen for the noun. the most energetic form of electromagne ...

UV astronomy,
neutrino astronomy
Neutrino astronomy is the branch of astronomy that observes astronomical objects with neutrino detectors in special observatories. Neutrinos are created as a result of certain types of radioactive decay, nuclear reactions such as those that take p ...
, and studies of
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 hole
A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can defo ...

active galactic nuclei
An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much-higher-than-normal luminosity over at least some portion of the electromagnetic spectrum with characteristics indicating that the luminosity is not prod ...

supernovae,
kilonovae,
supernova remnants, and
gamma ray bursts.
Missions
Some space and ground-based telescopes that have studied high energy astronomy include the following:
*
AGILE
