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).
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.
