Cosmology is the study of the Universe as a whole. While astronomy studies individual celestial objects such as stars, planets, galaxies, and cosmology focuses on the big picture: How the Universe works, how it came to be, and how it might end. We study the structure of galaxies and the structure of space-time (warpage via black holes etc), the nature of time, mass and energy, string theory, and if there are actually other Universes, in a never-ending multiverse' or omniverse. Cosmology differs from Astronomy. Astronomy seems to concentrate on the star names and the description of the Earth in the solar system. The cosmology concentrates more on the physiology of the Universe.
