Astrophysics Terms flashcards are a set of study cards designed to help students learn and memorize important terms related to astrophysics. Each flashcard typically contains a term on one side and its definition on the other side, making it easy for students to quiz themselves or study with a partner.
Astrophysics is a branch of astronomy that deals with the physical properties and processes of celestial bodies and the universe as a whole. It combines principles of physics and astronomy to understand phenomena such as black holes, supernovae, and the origins of the universe.
