Clusters, the survivers of a 13-billion-year-old massacre.

‘The new work, led by Dr Diederik Kruijssen of the Max Planck Institute for Astrophysics in Garching, Germany, appears in a paper in the journal Monthly Notices of the Royal Astronomical Society.’ Our Milk Way Galaxy is enclosed in about 200 condensed groups of stars. These clusters can hold up to a million stars each. Believed to be as old as the universe it’s self, these are the last survivors’ of a 13-billion-year-old massacre. They were born when the first generations of galaxies and stars formed. A team of astronomers from Germany and the Netherlands have started computer-simulations that show how these stars were born. They find these clusters are the survivors of a 13-year-old massacre which abolished many of their younger cluster siblings. When galaxies clash, they often create incredible bursts of star formations (also called ‘starbursts’) and a ton of young, bright, and incredible stellar clusters varying in size.
