Apr 11, 2022 · About 99% of the material between the stars is in the form of a gas—that is, it consists of individual atoms or molecules. The most abundant elements in this gas are hydrogen and helium (which we saw are also the most abundant elements in the stars), but the gas also includes other elements.

The interstellar medium (ISM) is the matter and radiation that exists in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. It fills interstellar space and blends smoothly into the surrounding intergalactic space.

Apr 10, 2022 · About 15% of the visible matter in the Galaxy is in the form of gas and dust, serving as the raw material for new stars. About 99% of this interstellar matter is in the form of gas—individual atoms or molecules. The most abundant elements in the interstellar gas are hydrogen and helium.

The Interstellar Medium (ISM) is the material filling the space between the stars. It consists mainly of gas (99%) and dust (1%), mostly found in the form of clouds, or nebulae (plural of nebula). About 75% of the interstellar gas is in the form of hydrogen, and nearly all the remaining 25% as helium. This gas is extremely cold (around 10 K ...
