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 - Astronomers have discovered that the dwarf planet Snow White is an icy world, with about half its surface covered in water ice that once flowed from slush-spewing volcanoes. The dwarf planet may also be covered in a thin layer of methane. See article.
g Message - For centuries humans have looked at the stars and wondered “are we alone?” Now, setiQuest is an opportunity for you to help answer that question. In 1960, Frank Drake conducted the first scientific search for extraterrestrial intelligence (SETI). Since then, scientists from many countries have conducted more than 100 projects looking for communication signals from other civilizations. With the spread of the Internet in the 21st century, it is now possible for humans around the globe to participate in this new SETI program. You can participate as a software developer, signal detection algorithm developer, or a citizen scientist. See article.
g Cosmicus - NASA´s GRAIL mission to study the Moon is in final launch preparations for a scheduled launch on Sept. 8, 2011. 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
