Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Message - In SETI program planning, higher priority should be given in the near-term to those probe and artifact searches which can be carried out quickly and inexpensively, in preference to larger more expensive beacon searches which should be mounted in the decades ahead. See article.
g Cosmicus - Where will MSL land? NASA has narrowed the options down to two potential sites on the red planet. See article.
g Aftermath - Here’s an intriguing paper published earlier this year and translated from German for Astrosociology.com: “Futurological Reflections on the Confrontation of Mankind with an Extraterrestrial Civilization”.

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
