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 - Scientists using data from the W. M. Keck Observatory have found the strongest evidence yet that salty water from the vast liquid ocean beneath Europa’s frozen exterior actually makes its way to the surface. See article.
g Intelligence - A study published in the February 2013 issue of the Journal of the American Academy of Child and Adolescent Psychiatry found that children and adolescents with major depression or subthreshold forms of bipolar disorder - and who had at least one first-degree relative with bipolar disorder - responded better to a 12-session family-focused treatment than to a briefer educational treatment. See article.
g Message - Here’s a classic essay on SETI: Carl Sagan’s “The Quest for Extraterrestrial Intelligence”.

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
