The “Innovations” program highlighted the discovery by a team of astrophysicists of the way stars are formed. And they solved this puzzle through an innovative simulation process. A team that included members from Northwestern University, Carnegie Observatories, Harvard University, and California Institute of Technology performed a highly detailed 3D simulation of star formation in the most realistic and accurate way to date. The results showed that star formation is a self-organizing process, which means that the star determines its mass on its own, which helped explain why the masses of stars are similar, even though they form in different environments. , a mystery that has occupied the interest of astrophysicists for decades.
