Looking for habitable planets in the galactic center
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 - Though stars closer to the galactic center are exposed to more radiation, new research finds that there are more chances to find habitable planets there than in the outer regions of our galaxy. See article.
g Cosmicus - Combining data from the Herschel Space Observatory with cloud models of Saturn has helped scientists understand how plumes of water vapor and ice from Enceladus affect the chemical composition of Saturn. See article.
g Imagining - Like stories about efforts to communicate with alien? Then be sure to read Fred Hoyle’s “A for Andromeda” (1962). 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
