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 - NASA’s Radiation Belt Storm Probes mission will send two spacecraft into the harsh environment of our planet’s radiation belts. See article.
g Message - On August 15, with the push of a few buttons, a Twitter experiment of galactic proportions will launch from Earth into the cosmos.b See article.
g Cosmicus - New data from the Voyager 1 spacecraft has revealed that three key signs of changes expected to occur at the boundary of interstellar space have changed faster than at any other time in the last seven years. Data from Voyager includes measurements of high-energy cosmic rays from outside the Solar System, low-energy particles originating from inside the Solar System, and studies on the direction of the magnetic field.

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
