|Astronomers have uncovered, for the first time, how our Milky Way galaxy formed and evolved over nearly 14 billion years of the Universe's life. The team say they could potentially change scientific thinking in one of the most fascinating fields in astronomy. When massive stars "die' they explode spectacularly and return most of the chemical elements out of which us, our planet, and our solar system formed, as well as an enormous amount of energy into the surrounding gas. The results have enormous significance for Gaia satellite mission which has been designed to mine the fossil record of the Milky Way. "The physics driving the formation and evolution of galaxies is of huge importance in the scientific research journey to understanding our origins. By demonstrating that we finally have been able to simulate such systems, we can enter the Gaia era with a greater degree of confidence.|
