Extraterrestrial Studies is the scientific investigation of life beyond Earth. This field explores the possibility of life on other planets, moons, and celestial bodies. Researchers use various methods, including telescopes and space missions, to gather data about potential habitats and the conditions necessary for life. One key aspect of Extraterrestrial Studies is the search for exoplanets, which are planets outside our solar system. Scientists analyze the atmospheres of these planets for signs of biosignatures, or indicators of life. Additionally, missions like Mars Rover and Europa Clipper aim to explore specific locations within our solar system for evidence of past or present life.
