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 - New data suggests that Gliese 581g is indeed an exoplanet, and is currently the best candidate for a potential habitable world. See article.
g Life - By performing high-pressure studies of proteins, scientists are learning how deep-sea bacteria adapt to the environment in which they live. See article.
g Cosmicus - NASA's Opportunity Mars rover, which landed on Mars in 2004, is on track to complete the first extraterrestrial marathon. Opportunity has traveled almost 22 miles so far during its mission, collecting valuable data about the Martian environment. 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
