Exobiology is the scientific study of life beyond Earth. It explores the potential for life on other planets and moons, examining the conditions that might support living organisms. Researchers in this field investigate extreme environments on Earth, such as deep-sea vents and polar regions, to understand how life can adapt and survive in harsh conditions. The field also involves the search for extraterrestrial life through missions to places like Mars and the icy moons of Jupiter and Saturn. Scientists analyze data from telescopes and space probes to identify signs of life, such as organic molecules or unusual atmospheric conditions.
