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 - Images of a remarkable crater on Mars show that the planet's climate fluctuated due to changes in its rotation axis. See article.
g Cosmicus - Traveling 300 million miles through deep space to reach the planet Mars is difficult; successfully landing there is even harder. The process of entering the Red Planet's atmosphere and slowing down to land has been described as "six minutes of terror." See article.
g Learning - Through fantastic original artwork and a compelling storyline, this series of graphic novels chronicles the origin and evolution of astrobiology itself. Produced by the NASA Astrobiology Program, the series began in 2010 to celebrate the 50th anniversary of Exobiology and Astrobiology at the National Aeronautics and Space Administration. 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
