Glossary term: Astrophysics

Description: Astrophysics is a science that employs the principles of physics to study the nature of astronomical objects. In astrophysics, the radiation across the entire electromagnetic spectrum, together with non-electromagnetic signals, such as gravitational waves and neutrinos emitted by astronomical objects, are studied, alongside their properties in terms of brightness, density, and temperature. Astrophysics is a very broad science that includes branches of theoretical and observational physics.
