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 - By studying fossil raindrops, scientists have revealed valuable information about the early atmosphere of Earth. The research could dramatically improve models of Earth's ancient, and will help astrobiologists understand the environmental conditions in which life arose on our planet. See article.
g Life - Researchers are moving closer to understanding how cells begin to duplicate their DNA, and ultimately replicate themselves. The study sheds new light on processes that underlie the origin and evolution of life as we know it. See article.
g Cosmicus - NASA is extending three missions that will continue to play an important role in the search for habitable planets beyond our solar system. 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
