habitabilitet
Habitabilitet, or habitability, is the potential of an environment to support life. In planetary science, it refers to the conditions that would allow life, chemistry, energy, temperature range, and liquid water, to persist for long enough to originate and evolve. Habitability is a spectrum rather than a binary property; a body may be more or less capable of supporting life, or hospitable to certain forms only.
Key factors include a source of energy, stable temperatures, and the presence of liquid water, a suitable
Habitability can apply to various environments: surface habitability for rocky planets, subsurface habitability in ice-covered moons
Scientists assess habitability using climate models, atmospheric chemistry, and observations of exoplanets, combined with the search
While unknowns remain, habitability remains central to astrobiology and the search for life beyond Earth.
