Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - What is the potential habitability of Barnard’s Star, the second closest solar system to Earth? See article.
g Abodes - NASA's Dawn spacecraft spent the last four years voyaging to asteroid Vesta - and may have found a planet. See article.
g Aftermath - Given the plethora of New Age/UFOlogy Web sites about alien contact, it’s refreshing to find one that’s serious. Try the “extraterrestrial intelligence, implications following first contact” entry at astrobiologist David Darling’s site “The Encyclopedia of Astrobiology, Astronomy, and Spaceflight”. It includes some links and a mini reference list.

The Drake Equation
This formula estimates the number of intelligent civilizations in our galaxy.N=(R*)(Ns)(Fp)(Ne)(Fl)(Fi)(Fc)(L)
Where:- N = Number of civilizations we can communicate with
- R* = Average star formation rate
- Ns = Percentage of stars capable of supporting earth-like planets
- Fp = Percentage of those stars with planets
- Ne = Average umber of planets in those stars' habitable zones
- Fl = Percentage of those planets where life begins
- Fi = Percentage of planets with life where an intelligent species evolves
- Fc = Percentage of those intelligent species that develop communication technology
- L = Average lifetime, in years, of a civilization that develops such technology
