WebMay 17, 2024 · ISM is composed primarily of hydrogen in its atomic, ionic, or molecular form and dust particles. Two forms of ISM are distinguished: interstellar diffuse clouds and IMCs. Interstellar diffuse clouds consist of atomic hydrogen. They can have kinetic temperatures of 50–100 K and a density of hydrogen atoms below 300 per cm 3. WebThe interstellar gas is typically found in two forms: Cold clouds of neutral atomic or molecular hydrogen; and Hot ionized hydrogen near hot young stars.

Molecular cloud - Wikipedia

WebA molecular cloud, sometimes called a stellar nursery (if star formation is occurring within), is a type of interstellar cloud, the density and size of which permit absorption nebulae, the formation of molecules (most commonly molecular hydrogen, H 2), and the formation of H II regions.This is in contrast to other areas of the interstellar medium that contain … WebApr 11, 2024 · Summary. Interstellar gas may be hot or cold. Gas found near hot stars emits light by fluorescence, that is, light is emitted when an electron is captured by an ion and cascades down to lower-energy levels. Glowing clouds (nebulae) of ionized hydrogen are called H II regions and have temperatures of about 10,000 K. port removal surgery steps https://oscargubelman.com
