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 - Enough water to fill Earth's oceans more than 2000 times over has been discovered in a cloud of gas and dust that is on the verge of collapsing into a new Sun-like star. The finding could help astrobiologists understand the conditions of the early Solar System. See article.
g Life - With funding from the NASA Astrobiology Institute, scientists are developing and testing instruments and techniques to detect life deep below Earth's surface. See article.
g Cosmicus - Michael Meyer, the lead scientist for NASA’s Mars program, talks about his role in developing the Curiosity rover that’s now exploring the surface of Mars. 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
