What is a cloud of gas and dust called?
In this regard, what's an interstellar cloud of gas or dust?
An interstellar cloud is generally an accumulation of gas, plasma, and dust in our and other galaxies. Put differently, an interstellar cloud is a denser-than-average region of the interstellar medium, (ISM), the matter and radiation that exists in the space between the star systems in a galaxy.
Furthermore, what is a diffuse cloud? diffuse cloud. A small atomic (H I) cloud that has too low a column density for it to be observed visually. Diffuse clouds constitute the bulk of the cold neutral medium in the three-phase description of the interstellar medium.
In this way, what are space clouds called?
The glowing clouds that you see in pictures from space are called emission nebulas. A emission nebula is a cloud of hot, glowing cloud of gas and dust in space. These nebulas absorb the light of nearby stars and reach very high temperatures.
How do gas clouds form in space?
Stars form inside relatively dense concentrations of interstellar gas and dust known as molecular clouds. At these temperatures, gases become molecular meaning that atoms bind together. CO and H2 are the most common molecules in interstellar gas clouds. The deep cold also causes the gas to clump to high densities.
