Local Interstellar Cloud (LIC)
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.

of galactic clouds, including the Local Interstellar Cloud (figure
