What is Lifecycle of Molecular Clouds in Galaxies about?
This study investigates the lifecycle of giant molecular clouds (GMCs) in nine nearby star-forming disc galaxies using a new statistical method to measure their evolutionary timeline. The findings reveal that GMCs have short lifetimes of 10–30 million years, influenced by environmental factors, and experience a long inert phase before dispersing rapidly due to stellar feedback. The research highlights the importance of GMCs and H II regions in the star formation process and suggests future studies should fu
