WitrynaThis gas and dust is not distributed uniformly in interstellar space, but displays significant variations in density, temperature, and ionization state. How is the interstellar medium distributed? Distribution of Interstellar Matter Interstellar matter is mostly gaseous, but about 1% is interstellar grains or dust.
Witryna9 kwi 2024 · 20.1: The Interstellar Medium. 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. summer chemistry coursesIn astronomy, the interstellar medium (ISM) is the matter and radiation that exist 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.
