The field of cosmology has experienced an explosion of activity since the discovery of ripples in the energy of the primordial light of the big bang by the COBE satellite in 1992.
Cosmology is the study of the origin, evolution, and fate of objects in the observable universe. These include galaxies like our Milky Way, a vast collection of stars spanning many thousands of light years. The key to the birth and evolution of such objects lies in the primordial ripples observed through light shining through from the early universe.
