kaasukehäisiä

Kaasukehäisiä is a Finnish term that translates to "gaseous" or "related to a gas envelope" in English. It is most commonly used in scientific contexts, particularly in astronomy and atmospheric science, to describe celestial bodies or phenomena that possess a substantial atmosphere.

In astronomy, kaasukehäisiä is often used to refer to planets like Jupiter, Saturn, Uranus, and Neptune, which are known as gas giants. These planets are characterized by their massive atmospheres composed primarily of hydrogen and helium, with little to no solid surface. The term can also be applied to exoplanets that exhibit similar atmospheric characteristics, even if their exact composition is not fully understood.

In atmospheric science, kaasukehäisiä might describe the atmospheric layers of a planet or moon, or specific gaseous phenomena within an atmosphere. For instance, it could be used to discuss the process of atmospheric escape from a planet, where gases gradually leave the planet's gravitational pull, or to describe the conditions within the upper layers of Earth's atmosphere. The concept of a "kaasukehä" (gas envelope) is central to understanding planetary formation, climate, and the potential for life beyond Earth.
