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 - Do supermassive black holes prune galaxies? See article.
g Abodes - The Curiosity rover has completed a “brain transplant,” transitioning to new software for Mars surface operations. The new software was uploaded to the rover's memory during the flight from Earth, and adds new capabilities that will help Curiosity explore the surface of Mars. See article.
g Cosmicus - Don Pettit recounts life on the International Space Station as part of the Expedition 31 crew. Some of his unique experiences include using chopsticks in microgravity, and orbiting in the Earth in perpetual twilight. 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
