Fr.: bulle interstellaire
A huge structure of ionized gas blown into the interstellar medium by the winds of supernovae and massive stars. → Local Bubble.
Fr.: nuage interstellaire
An aggregation of gas and dust in the → interstellar medium containing large quantities of atoms, molecules, and dust. There are several types of interstellar clouds, such as → diffuse interstellar clouds, → dark clouds, → molecular clouds.
Fr.: poussière interstellaire
An aggregation of → dust grains in the space between stars. Interstellar dust absorbs, scatters, and polarizes the light from distant stars, causing the → interstellar extinction.
