The diversity found in the different types and scales of astronomical objects make the field of study increasingly specialized.A proposed timeline of the origin of space, from physical cosmology
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[4]
Space chemistry – Reactions of elements to form more complex compounds, such as amino acids, are key to the study of chemistry in space.[5]
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.
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.
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:
Space technology is technology for use in outer space, in travel or other activities beyond Earth's atmosphere, for purposes such as spaceflight, space exploration, and Earth observation.
