Difference between Interstellar medium and Stellar classification

Interstellar medium vs. Stellar classification

In astronomy, the interstellar medium (ISM) is the matter and radiation that exists in the space between the star systems in a galaxy. In astronomy, stellar classification is the classification of stars based on their spectral characteristics.

Similarities between Interstellar medium and Stellar classification

Interstellar medium and Stellar classification have 29 things in common (in Unionpedia): Alnilam, Astronomy, Calcium, Carbon, Electromagnetic radiation, Galaxy, Helium, Hydrogen, Hydrogen line, Infrared, Kelvin, Metallicity, Milky Way, Molecular cloud, Molecule, Nebula, Nitrogen, Orion (constellation), Oxygen, Planetary nebula, Protoplanetary disk, Sodium, Star, Stellar evolution, Stellar wind, Sun, The Astrophysical Journal, Ultraviolet, Wavelength.

Alnilam

Alnilam, designated Epsilon Orionis (ε Orionis, abbreviated Epsilon Ori, ε Ori) and 46 Orionis (46 Ori), is a large blue supergiant star some 2,000 light-years distant in the constellation of Orion.

Infrared

Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.
