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 - What is the potential habitability of Gliese 628, a M-type star less than 14 light years from Earth? See article.
g Abodes - Scientists have put together the first comprehensive maps of the Moon's surface. Studying the Moon's surface can provide clues about the processes that shaped the Moon and, ultimately, the early Earth. See article.
g Message - In August 1977, a sky survey conducted with Ohio State University's "Big Ear" radio telescope found what has become known as the 'Wow” signal. Registering an enormous signal strength, the shape of the signal had the characteristic rise and fall expected for its short 72 second lifetime. 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
