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 TZ Arietis, a M-type star less than 15 light years from Earth? See article.
g Abodes - New research indicates that planets around stars are the rule rather than the exception in our galaxy. If planets are common in the Milky Way, it could increase the likelihood that habitable worlds exist somewhere beyond our own solar system. See article.
g Life - Researchers studying the origin of life are investigating genetic molecules that could have pre-dated DNA and RNA. See article.
g Learning - Astrobiology Magazine welcomes the addition of the Pale Blue Blog, a unique collection of individual bloggers who voice their opinions on matters concerning life's potential on planets beyond 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
