6.   radiation to modern astronomy and astrophysics

Answer 2

Introduction to modern astronomy and astrophysics, including basic principles of mechanics, gravity, optics, radiation, and observational and experimental methods. A main theme is to explore how these principles affect the evolution of our scientific understanding of astronomical phenomena.

Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates outside Earth's atmosphere. Cosmology is a branch of astronomy. It studies the Universe as a whole.

Professional astronomy is split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects. This data is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. These two fields complement each other. Theoretical astronomy seeks to explain observational results and observations are used to confirm theoretical results.
