For example, the big bang, the origin of the chemical elements, and the cosmic microwave background are all subjects of cosmology.

Detailed explanation-5: -ASTROPHYSICS: Applying the laws of physics in space. ASTROMETRY: Mapping celestial bodies. ASTROGEOLOGY: Examining rocks, terrain, and material in space. ASTROBIOLOGY: Searching for life outside Earth. 12-May-2022
