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 have discovered a layer of liquefied molten rock in Earth's mantle. This magma layer could act as a lubricant for our planet's tectonic plates. See article.
g Life - Scientists have uncovered new information about Earth's early oceans during a period of time that was critical to the evolution of complex life. See article.
g Message - An idea to send radar signal with Morse code to the Venus and to receive echo in order to test and to demonstrate the first Evpatoria Planetary Radar was suggested and implemented in 1962 by three scientists from Institute of Radio Engineering and Electronics in the former Soviet Union. While this transmission was not proper Interstellar Radio Message, it was its forerunner. See article. For related article, see “Report on Cosmic Call 1999”.

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
