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 - Curiosity has found evidence of a stream that once ran vigorously across the surface of Mars. This is the first evidence of its kind for ancient water on Mars. See article.
g Life - New research on a lizard-like amphibian highlights how difficult it would be for humans to regenerate a limb or organ. See article.
g Learning - In wanting to better assess whether life could be elsewhere, astrobiology has also set out on the more homely tasks of understanding how life evolved on the Earth, how life has persisted on our own planet for over three-and-a-half billion years and how it manages to thrive in extremes that to humans seem completely inimical to life. 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
