  Extremophiles teach us about the potential for life to exist in extreme conditions, such as high radiation, extreme temperatures, and high acidity. By studying these organisms, scientists can hypothesize about life forms that might exist on other planets with similar harsh environments.

• How does astrobiology impact our understanding of Earth's future?

  Astrobiology can provide valuable insights into Earth's future by helping us understand how life can adapt to changing conditions. This knowledge can inform efforts toward sustainability and resilience, ensuring that life on Earth continues to thrive despite environmental challenges.
