Astronomy

Astronomy is a broad and complex field of study that encompasses many different sub-disciplines. Here are some of the major sub-disciplines of astronomy:

Astrophysics

Astrophysics is the study of the physical properties and behavior of celestial objects such as stars, galaxies, and black holes. It involves applying the principles of physics and other sciences to the study of astronomical objects.

Planetary Science

Planetary science is the study of planets, moons, and other celestial bodies within our solar system. It includes the study of their geology, atmospheres, and the potential for life.

Cosmology

Cosmology is the study of the universe as a whole, including its origins, evolution, and large-scale structure. It seeks to understand the universe on the largest scales, including the formation of galaxies and the evolution of the universe as a whole.

Astrobiology

Astrobiology is the study of the origin, evolution, and distribution of life in the universe. It involves the study of the conditions necessary for life to exist, the search for extraterrestrial life, and the potential for life to exist beyond Earth.

Exoplanet Astronomy

Exoplanet astronomy is the study of planets outside our solar system. It involves the search for exoplanets, the study of their properties, and the potential for life to exist on these worlds.

Stellar Astronomy

Stellar astronomy is the study of stars, including their properties, evolution, and behavior. It involves the study of star formation, the life cycles of stars, and the study of stellar remnants such as white dwarfs, neutron stars, and black holes.
