Habitability refers to the ability of an environment to support life. This concept is often applied to planets, moons, and other celestial bodies, assessing whether they have the necessary conditions, such as temperature, atmosphere, and water, to sustain living organisms. For example, Earth is considered highly habitable due to its stable climate and abundant resources. In the search for extraterrestrial life, scientists study the habitability of places like Mars and the moons of Jupiter and Saturn. Factors such as the presence of liquid water, suitable temperatures, and protective atmospheres are crucial in determining whether these locations could support life forms similar to those on Earth.
