Local Interstellar Cloud (LIC)

Local Interstellar Cloud

The Sun and the nearest stars move through filaments of galactic clouds, including the Local Interstellar Cloud (figure by P. C. Frisch, University of Chicago).

The Local Interstellar Cloud (LIC) is a cloud of neutral hydrogen that is flowing away from the Scorpius-Centaurus Association and through which the Sun is currently passing. The LIC resides in a low-density hole in the interstellar medium known as the Local Bubble. Nearby, high-density molecular clouds, including the Aquila Rift, surround star-forming regions.
