Outline of astronomy

Mauna Kea in Hawaii is one of the world's premier observatory sites. Pictured is the W. M. Keck Observatory, an optical interferometer.

The following outline is provided as an overview of and topical guide to astronomy:

Astronomy – studies the universe beyond Earth, including its formation and development, and the evolution, physics, chemistry, meteorology, and motion of celestial objects (such as galaxies, planets, etc.) and phenomena that originate outside the atmosphere of Earth (such as the cosmic background radiation).

Nature of astronomy

Astronomy can be described as all of the following:

  • An academic discipline: one with academic departments, curricula and degrees; national and international societies; and specialized journals.
  • A scientific field (a branch of science) – widely-recognized category of specialized expertise within science, and typically embodies its own terminology and nomenclature. Such a field will usually be represented by one or more scientific journals, where peer reviewed research is published.

Branches of astronomy

The subdisciplines of observational astronomy are generally made by the specifications of the detectors:

General techniques for astronomical research are also convenient ways of dividing the field:

  • Photometry – study of how bright celestial objects are when passed through different filters
  • Spectroscopy – study of the spectra of astronomical objects
  • 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.

Other disciplines that may be considered part of astronomy:
