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 - Previously, many scientists though that Earth was the only planet in our solar system with tectonic plates. New research now shows that the geological phenomenon may also be present on Mars. See article.
g Life - New research is shining a light on the mysterious lives of methane-exhaling microbes that live deep in the cracks of hot undersea volcanoes. See article.
g Learning - A recent National Geographic Society poll reported that 36 percent of Americans -- about 80 million people -- believe UFOs exist, only 17 percent do not, and the rest of the people are undecided. The survey did not specifically equate UFOs with flying saucers or little green men, however. 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
