Exobiology (or Astrobiology)
Modern biological studies on Earth find (simple) life existing in what was once thought to be too extreme of conditions. This suggests life can be highly flexible and adaptable, giving scientists much to think about. Exobiology has become a major new direction of valid scientific research.
