Extraterrestrial research involves the scientific study of life beyond Earth. This field includes the search for signs of life on other planets, moons, and celestial bodies, as well as the investigation of unidentified flying objects, or UFOs. Scientists use telescopes, space missions, and robotic probes to gather data about potential habitats for life. One of the key goals of extraterrestrial research is to understand the conditions that could support life. This includes studying extreme environments on Earth, such as hydrothermal vents and Antarctica, to learn how life might exist in similar conditions elsewhere in the universe.
