Branches of space sciences:
– Astronomy:
– Astrophysics deals with the physics of the universe
– Subfields include computational astrophysics and plasma astrophysics
– Solar physics studies the Sun and its interactions
– Galactic astronomy focuses on our galaxy and others
– Extragalactic astronomy studies objects outside our galaxy

– Cosmology:
– Physical cosmology studies the origin and evolution of the universe
– Chemical cosmology examines the chemical composition of matter
– Quantum cosmology uses quantum field theory to explain phenomena
– Planetary Science includes the study of planets and moons
– Astrochemistry studies molecules in the Universe

– Interdisciplinary studies of astronomy:
– Astrobiology studies biological systems in the universe
– Space biology looks at how spaceflight affects living systems
– Astrobotany studies plants in space environments
– Archaeoastronomy analyzes ancient astronomies
– Space archaeology studies human artifacts in outer space

– Techniques used in astronomical research:
– Theoretical astronomy involves mathematical modeling
– Astrometry studies the position of objects in the sky
