Extraterrestrial

"Extraterrestrial" refers to anything originating outside Earth’s atmosphere. It commonly describes life forms, objects, or phenomena that are not part of our planet. For example, a space probe exploring Mars is studying extraterrestrial environments, and potential alien life is considered extraterrestrial life. The term helps distinguish between things that are native to Earth and those that come from elsewhere in the universe, whether it’s distant planets, moons, or even other galaxies. It’s a scientific way to discuss phenomena beyond our planet, often associated with space exploration and the search for life beyond Earth.
