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 - Some people are in great shape at the age of 90, while others are decrepit before they're 50. We know that how fast people age is only loosely linked to how old they actually are - and may have more to do with their lifestyle. A new study with the NASA/ESA Hubble Space Telescope reveals that the same is true of star clusters. See article.
g Abodes - The first truly Earth-like alien planet is likely to be spotted this year, an epic discovery that would cause humanity to reassess its place in the universe. See article.
g Aftermath - At some point we may discover intelligent alien life. Upon finding clear evidence that intelligent life exists and that we could conceivably communicate with them on their planet, what should we do and what would we do? 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
