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 - As a star grows older, its rotation slows down steadily. Now, astronomers have discovered how to use this principle to determine the age of stars. The research could ultimately help astrobiologists understand the nature of planets and the stars they orbit. See article.
g Abodes - New visualizations of the Earth from space provide a unique image of how the Earth has changed over the past 750 million years. See article.
g Life - A new study shows that random introduction of errors into proteins may have boosted the evolution of biological complexity. 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
