Astrophysics (index)about


(study of extra-terrestrial life)

Astrobiology is the study of life off of Earth. None has been found so it is a bit speculative. The study includes:

  • Modeling and search for signs of life such as compounds rare in nature but plentiful on Earth because of life.
  • Modeling the conditions that would support the development and continuation of life such as Habitable Zones.
  • Searches for signs of life in planetary visits such as on Mars.
