The gas and dust in the interstellar medium are distributed in a somewhat clumpy manner, with denser regions referred to as interstellar clouds. The least dense of these are called diffuse clouds or HI (atomic hydrogen) clouds, while denser regions are, naturally, called dense clouds or molecular clouds.
