Surveys for atomic hydrogen at very high velocities (|V| ≥ 140 km s–1) in the galactic center and anticenter regions of the sky reveal a net inflow of gas toward the Milky Way. In the anticenter, the collisions of infalling clouds with galactic material trigger the most energetic structural disturbance in the Galaxy, the “anticenter supershell”.
