a huge cloud of dust and gas from which stars form?
nebula
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. depending on the density, size, and temperature of a given cloud, its hydrogen can be neutral, making an h i region; ionized, or plasma making it an h ii region; or molecular, which are referred to simply as molecular clouds, or sometime dense clouds. neutral and ionized clouds are sometimes also called "diffuse clouds". an interstellar cloud is formed by the gas and dust particles from a red giant in its later life.

like most star-forming regions, the interstellar medium around rcw 36 contains both the gas from which stars form and some newly formed young stars. here, young stellar clusters form in giant molecular clouds. molecular clouds are the coldest, densest form of interstellar gas and are composed mostly of molecular hydrogen (h), but also include more complex molecules, cosmic dust, and atomic helium. stars form when the mass gas in part of a cloud becomes too great, causing it to collapse due to the jeans instability. most stars do not form alone, but in groups containing hundreds or thousands of other stars. rcw 36 is an example of this type of "clustered" star formation.
