How is gas distributed in interstellar space
WebInterstellar gas contains other elements besides hydrogen. Many of them are also ionized in the vicinity of hot stars; they then capture electrons and emit light, just as hydrogen … Web14 mei 2024 · The components of the interstellar gas include: cold atomic gas clouds, warm atomic gas, the coronal gas, HII regions (a volume of space where hydrogen [H] is in an ionized state rather than in its usual neutral state), and molecular clouds. Most of the atoms in space are hydrogen, about 90%.
