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 - Researchers have developed a new model of brown dwarf formation. Understanding how these low mass objects form and evolve can help astrobiologists understand their potential for supporting solar systems with habitable planets. See article.
g Abodes - Linked to the close of the Mayan calendar, a variety of rumors have spread regarding ways the world could end in 2012. One popular contender is Nibiru, a supposed planet that some claim will collide with Earth at the end of the year. But despite the buzz, there is no scientific evidence supporting the alleged planet's existence. See article.
g Cosmicus - The European Space Agency has selected its next large science mission - the Jupiter Icy moons Explorer (JUICE). JUICE is set to launch in 2022 and will study the diverse moons of Jupiter and their potential as habitats for life. 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
