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 - Scientists have long thought that planets had to orbit very close to small and dim red dwarf stars in order to be warm enough for life. New research challenges that assumption. See article.
g Abodes - A new study shows that portions of the Earth's mantle formed when the planet was smaller, and survived the planet's turbulent formation and the collision that led to the creation of the Moon. See article.
g Intelligence - The more afraid a person is of a spider, the bigger that individual perceives the spider to be, new research suggests. See article.
g Cosmicus - After a two-year delay, a human daredevil is now preparing to step out of a stratospheric balloon and attempt the highest freefall jump ever. 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
