Multiscale Interstellar Medium Model

A Multiscale Interstellar Medium (ISM) Model is a scientific framework that describes the gas, dust, and magnetic fields in space between stars across different size scales—ranging from tiny particles to vast clouds. It integrates processes occurring at small scales, like star formation, with larger structures such as galaxy-wide gas flows. This comprehensive approach helps scientists understand how matter moves, evolves, and influences the development of stars and galaxies over time. Essentially, it's a detailed map of the complex, interconnected environment between stars, spanning many levels of size and activity.
