Branches of Astronomy

Branches of astronomy Wiki Astrobiology - the study of the advent and evolution of biological systems in the universe. Compact objects - the study of the very dense matter in white dwarfs and neutron stars and their effects on environments including accretion. Exoplanet studies - the study of the various planets outside of the solar system Cosmology - the study of the origin and evolution of the universe as a whole. The study of cosmology is theoretical astrophysics at its largest scale. Galaxy formation and evolution - the study of the formation of the galaxies, and their evolution. Galactic astronomy - the study of the structure and components of our galaxy and of other galaxies. High energy astrophysics - the study of phenomena occurring at high energies including active galactic nuclei, supernovae, gamma-ray bursts, quasars, and shocks. Interstellar astrophysics - the study of the interstellar medium, intergalactic medium and dust. Extragalactic astronomy - the study of objects (mainly galaxies) outside our galaxy. Stellar astronomy - the study of the stars. Plasma astrophysics - the study of astrophysical plasmas. Relativistic astrophysics - the study of the effects of special relativity and general relativity in astrophysical contexts including gravitational waves, gravitational lensing and black holes. Stellar evolution - the study of the evolution of stars from their formation to their end as a stellar remnant. Star formation - the study of the condition and processes that led to the formation of stars in the interior of gas clouds, and the process of formation itself.
