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 - The famed North Star has been a beacon in the night sky throughout human history, but a new study reveals the star is actually closer to our solar system than previously thought. See article.
g Abodes - An analysis of mineral grains from the bottom of the western Grand Canyon indicates it was largely carved out by about 70 million years ago - a time when dinosaurs were around and may have even peeked over the rim, says a study led by the University of Colorado Boulder. See article.
g Cosmicus - Astronaut Don Pettit continues his diary from Expedition 31 on the International Space Station. In this installment he talks about observing solar phenomenon from Earth orbit, and the continued care of the plants he has been caring for on the ISS. 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
