• Subfields of astronomy:
• Astrophysics – branch of astronomy that deals with the physics of the universe, including the physical properties of celestial objects, as well as their interactions and behavior.{{cite web | title=astrophysics | publisher=Merriam-Webster, Incorporated | url=http://www.merriam-webster.com/dictionary/astrophysics | access-date=2011-05-22 }} Among the objects studied are galaxies, stars, planets, exoplanets, the interstellar medium and the cosmic microwave background; and the properties examined include luminosity, density, temperature, and chemical composition. The subdisciplines of theoretical astrophysics are:
• Computational astrophysics – The study of astrophysics using computational methods and tools to develop computational models.
• Plasma astrophysics – studies properties of plasma in outer space.
• Space physics – study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System.
• Solar physics – Sun and its interaction with the remainder of the Solar System and interstellar space.
• Stellar astronomy – concerned with Star formation, physical properties, main sequence life span, variability, stellar evolution and extinction.
• Galactic astronomy – deals with the structure and components of our galaxy and of other galaxies.
• Extragalactic astronomy – study of objects (mainly galaxies) outside our galaxy, including Galaxy formation and evolution.
• Cosmology
• Physical cosmology – origin and evolution of the universe as a whole. The study of cosmology is theoretical astrophysics at its largest scale.
• Chemical cosmology - study of the chemical composition of matter in the universe and the processes that led to those compositions.
• Quantum cosmology – the study of cosmology through the use of quantum field theory to explain phenomena general relativity cannot due to limitations in its framework.
• Planetary Science – study of planets, moons, and planetary systems.
• Atmospheric science – study of atmospheres and weather.
• Planetary geology
• Planetary oceanography
• Exoplanetology – various planets outside of the Solar System
• Astrochemistry – studies the abundance and reactions of molecules in the Universe, and their interaction with radiation.

• Interdisciplinary studies of astronomy:
• Astrobiology – studies the advent and evolution of biological systems in the universe.
• Space biology – studies to build a better understanding of how spaceflight affects living systems in spacecraft, or in ground-based experiments that mimic aspects of spaceflight{{cite web | url=https://science.nasa.gov/biological-physical/programs/space-biology | title=Space Biology Program | Science Mission Directorate }}
• Space chemistry – Reactions of elements to form more complex compounds, such as amino acids, are key to the study of chemistry in space.{{cite web | url=http://sta.ie/lesson/space-chemistry | title=Space chemistry | Science & Technology in Action }}
• Astrobotany – Sub-discipline of botany that is the study of plants in space environments.
• Archaeoastronomy – studies ancient or traditional astronomies in their cultural context, utilizing archaeological and anthropological evidence.
• Space archaeology – the study of human artifacts in outer space
• Forensic astronomy – the use of astronomy, the scientific study of celestial objects, to determine the appearance of the sky at specific times in the past.

• Techniques used in astronomical research:
• Theoretical astronomy – mathematical modelling of celestial entities and phenomena
• Astrometry – study of the position of objects in the sky and their changes of position. Defines the system of coordinates used and the kinematics of objects in our galaxy.
• Photometry – study of how bright celestial objects are when passed through different filters
• Spectroscopy – study of the spectra of astronomical objects
• Observational astronomy – practice of observing celestial objects by using telescopes and other astronomical apparatus. Observatories on the ground as well as space observatories take measurements of celestial entities and phenomena. It is concerned with recording data. The subdisciplines of observational astronomy are generally made by the specifications of the detectors:
• Radio astronomy – >300 μm
• Submillimetre astronomy – 200 μm to 1 mm
• Infrared astronomy – 0.7–350 μm
• Optical astronomy – 380–750 nm
• Ultraviolet astronomy – 10–320 nm
• High-energy astronomy
• Cosmic ray astronomy - charged particles with very high kinetic energy
• X-ray astronomy – 0.01–10 nm
• Gamma-ray astronomy – <0.01 nm
• Neutrino astronomy – Neutrinos
• Gravitational wave astronomy – Gravitons
