HandWiki:Astronomy

From HandWiki

Astronomy deals with celestial objects, space and the physical universe as a whole. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. This HandWiki portal covers cosmology, space science, space exploration, celestial objects and related phenomena.
