tussenstof

Tussenstof, also known as interstellar medium, refers to the matter that exists in the space between the star systems in a galaxy. This matter is primarily composed of gas in the form of hydrogen and helium, along with trace amounts of other elements. The interstellar medium plays a crucial role in the lifecycle of stars and galaxies. It provides the raw material for the formation of new stars and planets, and it also influences the evolution of galaxies through processes such as star formation and feedback from supernova explosions.

The interstellar medium can be broadly categorized into two types: the warm ionized medium and the cold

The interstellar medium is not uniformly distributed throughout a galaxy. Instead, it is structured into various
