The discovery of the Cosmic Microwave Background together with the observed Hubble expansion of the universe and the abundance of light elements had established the Big Bang cosmological model as a viable model of the universe. All basic principles of modern cosmology without going into difficult mathematics are presented. The standard Big Bang model and the different types of universe are summarized. The dark matter as the most mysterious component of the universe is introduced. The problems of Big Bang are discussed together with their resolution by inflationary cosmology. The history of the early universe and the temperature fluctuations of the Cosmic Microwave Background radiation are summarized. The current observational situation and perspectives of Planck mission are given in the end of this paper.
