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 the nearby star Groombridge 1618? See article.
g Life - What makes some species more prone to extinction? A new study of nearly 300 species of New Zealand birds - from pre-human times to the present - reveals that the keys to survival today differ from those of the past See article.
g Cosmicus - NASA's newest Mars mission is a bold step forward in our study of life's past and present potential on Mars. However, to accomplish its goals, the Curiosity rover will also draw on support from previous missions sent to Mars years ago. 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
