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 - A new study based on data from the Kepler mission indicates that planets as big as Earth but smaller than Neptune could be more common in our galaxy than previously believed. See article.
g Abodes - A new study reveals that ancient Antarctica was much warmer and wetter than previously expected. See article.
g Message - For some three decades, Dr. Jill Tarter, now 68, has been the person most likely to be the first to know if we make contact with E.T. — the one who will sound the alarm, spreading the news that We Are Not Alone. 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
