Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Astronomers have discovered evidence of a planet that has been destroyed by its aging star. The finding provides insight into the evolution of planetary systems, and the future of our own solar system. See article.
g Cosmicus - Curiosity's ChemCam zapped its first rock last weekend. Since then, the laser instrument has fired nearly 500 shots so far that have produced clear data abou the composition of the Martian surface. See article.
g Learning - "A lot of people couldn't figure out Armstrong." With those words Tom Wolfe introduced Neil Armstrong, the astronaut hero of his nonfiction masterpiece, "The Right Stuff." Armstrong, of course, was a masterpiece himself: the commander of the 1969 Apollo 11 mission and the first man ever to walk on the moon. Armstrong died Saturday from complications relating to heart surgery. He was 82. 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
