Gamma-ray astronomy is radiation astronomy applied to the various extraterrestrial gamma-ray sources, especially at night. It is usually conducted above the Earth's atmosphere and at locations away from the Earth as a part of explorational (or exploratory) gamma-ray astronomy.

Educational level: this is a secondary education resource.

An introduction to gamma rays may occur at the secondary education level. The study of this type of radiation usually intensifies at the university undergraduate level. The more hazardous aspects of gamma radiation become known when a student embarks on graduate study.

Educational level: this is a tertiary (university) resource.

As with general radiation astronomy some cautionary speculation may be introduced unexpectedly to stimulate the imagination and open a small crack in a few doors that may appear closed at present. This advances the learning portion of the resource to being a lecture and part article so some state-of -the-art results from the scholarly literature can be included.

Educational level: this is a research resource.

The laboratories of gamma-ray astronomy are limited to the observatories themselves and the computers and other instruments (sometimes off site) used to analyze the results.

Type classification: this is an article resource.

Resource type: this resource contains a lecture or lecture notes.

Subject classification: this is an astronomy resource.

Notation

To help with definitions, their meanings and intents, there is the learning resource theory of definition.

Notation: let the symbol Def. indicate that a definition is following.

Universals

Def. "[v]ery high frequency (and therefore very high energy) electromagnetic radiation emitted as a consequence of radioactivity", from Wiktionary gamma ray, is called a gamma ray.

Def. "electromagnetic radiation consisting of gamma rays", per Wiktionary gamma radiation, is called gamma radiation.

Gamma rays

"Most astronomical gamma-rays are thought to be produced not from radioactive decay, however, but from the same type of accelerations of electrons, and electron-photon interactions, that produce X-rays in astronomy (but occurring at a higher energy in the production of gamma-rays)." per the Wikipedia article gamma-ray astronomy.
