✴Cosmology is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is "the scientific study of the large scale properties of the universe as a whole."✴

►Cosmologists puzzle over exotic concepts like string theory, dark matter and dark energy and whether there is one universe or many (sometimes called the multiverse). While other aspects astronomy deal with individual objects and phenomena or collections of objects, cosmology spans the entire universe from birth to death, with a wealth of mysteries at every stage. ✦

►This App is aimed at students and readers who want to be able to understand and appreciate the Cosmological Phenomena we observe in the night sky. It will be of great importance to young astronomers, who wish to explore the night sky for finding astronomical objects.✦
