Galaxies can contain hundreds of billions of stars, but every one of those stars begins with cold, dense gas. Large galaxies, including the Milky Way, are surrounded by an enormous reservoir of this material known as the circumgalactic medium, or CGM. The CGM extends roughly 10-20 times farther than the visible part of a galaxy. Over time, some of this gas can cool, flow inward, gather into dense clouds, and eventually form new stars. Because stars give rise to planets and the conditions necessary for life, the CGM plays an important role in a galaxy's long term evolution.
