Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - A new study shows how tiny sea creatures called rhabdopleurids have survived for more than 500 million years and outlasted more elaborate species that descended from a common ancestor. See article.
g Cosmicus - In this interview, NASA scientist Danny Glavin describes how NASA’s Curiosity rover will be used to determine if the building blocks of life could have survived on the surface of Mars. See article.
g Aftermath - How will we react, the day we hear the news that scientists have found life on another planet? Science fiction writer Orson Scott Card has dreamed up many first contact scenarios. His classic science fiction novel, "Ender's Game" is all about the consequences of a first contact gone badly wrong. He's just published a long-awaited sequel. 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
