Astronomical sub-disciplines

thumb|Early 1900s comparison of elemental, solar, and stellar spectra

thumb|Nucleic acids may not be the only [[biomolecules in the universe capable of coding for life processes.]]

science of planets and other astronomical objects apparently in orbit around one or more stellar objects

branch of astronomy

subfield of astronomy that studies celestial objects at radio frequencies

The discipline overlaps with astronomy and chemistry. The term may refer to studies within both the Solar System and the interstellar medium. The investigation of elemental abundances and isotope ratios in Solar System materials, such as meteorites, is known as cosmochemistry, while the study of interstellar atoms and molecules and their interaction

branch of cosmology which studies mathematical models of the universe

thumb|The rising Sun illuminates the inner chamber of [[Newgrange, Ireland, only at the winter solstice.]]

branch of astronomy that uses X-ray observation

astronomy dealing with objects outside the Milky Way

study of the Milky Way galaxy and its contents

field of astronomy concerned with recording data about the observable universe

observational astronomy performed at less than 10 nm wavelengths

observational astronomy performed over the ultraviolet range from 10 nm to 400 nm

observational astronomy that benefits from the direct, or indirect, detection of neutrinos

astronomy of self-luminous gaseous celestial bodies of great mass whose shape is usually spheroidal and whose size may be as small as the earth or larger than the earth's orbit

type of astronomy involving observation of gravitational waves

interdisciplinary branch of physics

application of astronomical methods into geodesy

observation and interpretation of disparate "messenger" signals, created by different astrophysical processes like electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays

astronomy according to different culture

field of study on atomic and molecular particles in space

science of analysing historic astronomical data
