👉 Arrival biology, also known as xenobiology, is an emerging field that explores the potential biological forms and ecosystems that could exist if life were to arise on planets with radically different conditions from Earth. This includes considering environments with extreme temperatures, pressures, or chemical compositions, such as hydrothermal vents on icy moons like Europa or methane lakes on Titan. Scientists in this field hypothesize about the types of biochemistries that might develop under these alien conditions, including non-carbon-based life forms or organisms using alternative solvents like ammonia or liquid methane. By studying extremophiles on Earth—organisms that thrive in harsh environments—researchers gain insights into how life might adapt and evolve elsewhere, expanding our understanding of what life can be and where it might exist in the universe.
