From the Large Scale Universe to the Milky Way
The Universe has been constantly expanding and growing since it began its expansion. Although it seems to be very colorful and beautiful from pictures, it is very violent and destructive. Cosmology explains the origin and evolution of the Universe. From this, theories of the Big Bang and the formation of galaxies have arisen. Scientist discover new information from the Universe with the development of new technology and observation. Dark Matter is one of many new discoveries over the years. The Universe is full with celestial objects such as galaxies, dark matter, black holes, dark energy, and radiation they all play part in the development of each other.
Cosmology is the study of the origin and development of the Universe. This is much different from Astronomy. Astronomy is the observation of the observable Universe, whereas cosmology studies the evolution of the Universe. The Big Bang Theory is one of the modern foundations of modern cosmology. A Belgian priest named George Lemaitre first suggested the big bang theory in the 1920s, which was supported from Edwin Hubble's observation that galaxies are speeding away from us in all directions (Origins of the Universe). Hubble's expansion law, Microwave radiation, and COBE & WMAP experiments are all experimental tests of the Big Bang Theory that have been performed since 1929 (Welser-Sherrill, 2007). When the Big Bang occurred, it is believed that the heat would have been enormous and the remnant of heat found in cosmic microwave radiation is supports that theory.
Galaxies were one of the first celestial objects to form in the Universe. Our own galaxy the Milky Way was formed
