Interstellair medium
Interstellair medium (ISM) is de term die gebruikt wordt om alle materie (interstellaire materie, ook afgekort als ISM) en energie (interstellair stralingsveld), die zich tussen de sterren in een sterrenstelsel bevindt, aan te duiden. Voor materie en straling buiten sterrenstelsels wordt de term intergalactisch medium gebruikt. De chemische samenstelling en fysische eigenschappen (temperatuur, dichtheid en dynamica) van het ISM spelen een cruciale rol in de astrofysica: sterren worden gevormd uit het ISM (zie stervorming), en sommige sterren geven aan het einde van hun levensduur via supernova-explosies materiaal terug aan het ISM. In observationele astronomie is het ISM van belang omdat het invloed heeft op de energie afkomstig van sterren (in de vorm van fotonen) die waarnemers op de aarde kan bereiken.
