... A large fraction of the neutral atomic hydrogen (H I) in the Galaxy is hidden from direct view. Arcminute resolution 21 cm line maps from the Canadian Galactic Plane Survey (CGPS) reveal numerous cold hydrogen clouds as H I self-absorption (HISA) shadows against warmer background emission. HISA has traditionally been thought to trace the small fraction of atomic gas in molecular clouds. ...
