Interstellar Clouds
Interstellar clouds are vast regions of gas and dust located in between stars in a galaxy. These clouds are primarily composed of hydrogen and helium, with trace amounts of other elements. Interstellar clouds play a crucial role in the formation of new stars, as the gravitational collapse of these clouds can lead to the formation of protostars. Additionally, interstellar clouds are responsible for the production of heavy elements through nucleosynthesis, which are then dispersed throughout the galaxy by supernova explosions. The study of interstellar clouds is important for understanding the evolution of galaxies and the formation of planetary systems.
