400-Year-Old Cosmic Mystery Solved: New Class of Ancient Star System Discovered Hiding in Our Galaxy
New simulations suggest globular clusters form in multiple ways and point to a mysterious new type of star system that may already lie hidden in the Milky Way. For centuries, astronomers have tried to explain how globular clusters, among the oldest and densest stellar systems in the universe, fir
To probe the problem, Surrey researchers ran ultra-high-resolution simulations that follow the Universe’s 13.8-billion-year history in unprecedented detail, letting them watch globular clusters arise in real time inside a virtual cosmos called EDGE. A New Class of Object Dr Ethan Taylor, Postdoctoral Research Associate at the University of Surrey’s School of Mathematics and Physics and lead author of the study, said: “The formation of globular clusters has been a mystery for hundreds of years, so being able to add additional context surrounding how they form is amazing.
