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 - In one of the largest Hubble Space Telescope projects to date, astronomers are hoping to uncover how cosmic dust forms over time. The research is an important step in understanding the evolution of galaxies, stars and planets. See article.
g Intelligence - The unexpected survival of embryonic neurons transplanted into the brains of newborn mice in a series of experiments at the University of California, San Francisco raises hope for the possibility of using neuronal transplantation to treat diseases like Alzheimer's, epilepsy, Huntington's, Parkinson's and schizophrenia. See article.
g Cosmicus - Scientists are testing potential shielding for astronauts on long duration missions beyond Earth. Protecting astronauts from exposure to cosmic radiation is an important step in developing future missions to the Moon, Mars and beyond. 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
