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 - Researchers say life-bearing planets may exist in vast numbers in the space between stars in the Milky Way See article.
g Life - A fragment recovered from the "Sutter's Mill Meteorite," which fell to Earth on April 22, has been generously donated to NASA. Now, research on the meteorite fragment could bring answers to unsolved mysteries about our solar system and the origins of molecules necessary for life. See article.
g Cosmicus - NASA's Mars Exploration Rover Opportunity has driven off of Greeley Haven after surviving yet another Martian winter. Opportunity will now make its way toward veins in the bedrock on the northern edge of Cape York to study whether or not they contain minerals deposited by flowing water. 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
