Astronomy is a natural science that studies celestial objects and phenomena. 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 encyclopedia covers cosmology, space science, space exploration, celestial objects and phenomena.     [Add article.]
