Predictive modelling of galactic star and planet formation

Predictive modelling of galactic star and planet formation This article details advancements in our understanding of star and planet formation within galaxies, emphasising the transition from steady-state models to recognising the dynamic nature of the interstellar medium (ISM) in these processes. Modern astronomy has revealed that the Universe began in an extraordinarily simple state – almost perfectly uniform, with only minute fluctuations in density. Today, more than 13 billion years after the Big Bang, the cosmos is richly structured on every scale, from vast galaxy clusters down to stars, planets, and even complex organic molecules. In this cosmic hierarchy, galaxies – along with the stars and planets they contain – serve as fundamental building blocks. Understanding their origins and the physical processes that drive their evolution is one of the most significant challenges in contemporary astrophysics.
