Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - The Planetary Habitability Laboratory has created the Habitable Exoplanets Catalog, which assesses the habitability of exoplanets with the right size and orbit to be considered suitable for life. See article.
g Cosmicus - When the Mars Science Laboratory rover ‘Curiosity" lands on Mars in August 2012, its SAM instrument will "follow the carbon" to better understand the past and present habitability of our planetary neighbor. See article.
g Aftermath - Will we ever find a primer for decoding messages from extraterrestrials? Recently, anthropologists who gathered for a major conference in Atlanta heard some news that will be sobering for SETI enthusiasts: it may be much more difficult to understand extraterrestrials than many scientists have thought before. See article.

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
