Extragalactic Astronomy
Definition of Extragalactic Astronomy as it relates to Science, Space Science, Cosmology
Extragalactic astronomy focuses on celestial objects and phenomena beyond our own Milky Way galaxy, exploring the vast expanse of the universe to uncover its mysteries. This field encompasses the study of other galaxies, active galactic nuclei, quasars, cosmic background radiation, dark matter, and large-scale structure formation in the universe. By investigating these extragalactic entities, researchers aim to better understand the origins, evolution, and ultimate fate of the universe, making it an essential component of cosmological studies.
