Astronomy

Astronomy is the science that deals with the material universe beyond the earth. This includes individual celestial bodies, the universe as a whole, and the objects in it, including stars, planets, nebulae, and galaxies. Its various branches include astrometry, astrodynamics, cosmology, and astrophysics. Astronomers analyze not only visible light but also radio waves, x-rays, and other ranges of radiation that come from sources outside the Earth's atmosphere.
