tähtienvälisessä

tähtienvälisessä is a Finnish word that translates to "interstellar" in English. It describes phenomena, objects, or distances that exist or occur between stars. This term is frequently used in astronomy and science fiction.

In astronomy, the term "tähtienvälisessä" refers to the space between star systems. This region is not entirely empty but contains a very diffuse medium of gas and dust, known as the interstellar medium. Stars themselves, planets, nebulae, and other celestial bodies are also considered within the context of interstellar space. The vast distances involved are typically measured in light-years.

In science fiction, "tähtienvälisessä" travel is a common concept, referring to journeys between different star systems. This often involves hypothetical technologies like warp drives or hyperspace, which would allow spacecraft to traverse the immense distances in a reasonable amount of time. The exploration and colonization of exoplanets are frequently central themes in such narratives, all occurring within the scope of "tähtienvälisessä" settings.
