Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - By tracking atmospheric features on Neptune, scientists have determined the planet's rotation. It is the first time that such a feat has been achieved for a gas planet in our solar system other than Jupiter. See article.
g Cosmicus - Scientists are developing an artificial skin for robots that will improve the “perceptions” of robots. The science could have applications in the future of robotic space exploration. See article.
g Imagining - Hundreds of astronomers recently learned that life in outer space is likely to lack green eyes and be far more prosaic, tiny and, quite possibly, completely unlike life as we know it. This blunt appraisal came from the University of Washington's Center for Astrobiology and Early Evolution, one of the first programs in the country to give an advanced degree in astrobiology.

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
