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 - Astronomers have announced the first confirmed finding of oxygen molecules in space. See article.
g Abodes - New research shows that remnants of six of the largest volcanic events of the past 250 million years contain traces of Earth's primitive mantle. Such samples could provide information about the geochemical history of our planet. See article.
g Cosmicus - NASA has unveiled the first full-frame image of Vesta taken by the Dawn spacecraft. Vesta is the brightest object in the asteroid belt, and could provide clues about how rocky worlds formed and evolved in 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
