Therefore, the visible light of the universe explains the history of a star and when it was born.[[BR]][[BR]]We will learn how the birth of stars is connected with large structures of matter and the galaxies. The understanding of the history and the birth of stars plays a key role in understanding the universe and its evolution. This knowledge explains the assembly of structure in dark matter, tells us about physics behind the birth of stars and gas in galaxies and helps to understand the creation of heavy chemical elements, which finally lead to the generation of earth like planets and the live on it.[[BR]][[BR]]As of late, the history of stars can be observed with large telescopes from ground and space up to more than 12 billion years into the past and in short even to a 100 million years after the big bang. These observations are accompanied by enormous computer simulations to understand the physics in the stars and in the Galaxies better and better.
