Xenobiology is the study of life forms that may exist outside of Earth. It explores the potential characteristics, behaviors, and environments of extraterrestrial organisms. Scientists in this field consider how life could adapt to different conditions, such as extreme temperatures or varying atmospheric compositions. Researchers in xenobiology often draw on knowledge from biology, astrobiology, and chemistry to hypothesize about alien life. They examine extreme environments on Earth, like deep-sea vents and acidic lakes, to understand how life can thrive in harsh conditions, which may provide clues about life on other planets or moons.
