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 - Saturn’s moon Titan has been observed in detail for the past 30 years, that covers an entire solar orbit for this distant world. Researcher Dr Athena Coustenis from the Paris-Meudon Observatory in France has finished an analysis of the data that was gathered during this time period and has found that the changing seasons on Titan exert much more of an influence than had previously been thought. See article.
g Life - New research supports the idea that microorganisms embedded in the fragments of distant planets may have traveled to the early Earth and seeded our planet with life. See article.
g Cosmicus - Don Pettit, member of the Expedition 31 crew, discusses the treasures that spaceflight may hold for humanity. Research on the International Space Station is helping scientists understand how life as we know it functions, and how it adapts to the space environment. 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
