Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Scientists have created the first computer simulation of a spiral galaxy that matches our own Milky Way. See article.
g Message - Space probes sent by E.T.'s or machine life may not be interested in communicating with us but might consider us a limiting factor in their exploration or exploitation of a stars/planetary system's or galactic regions resources. One could surmise that it may be impossible for us to detect a probe that is just a little bit more advanced technologically than we are See article.
g Cosmicus - Providing food for astronauts may be one of the greatest challenges facing a human mission to Mars. The major challenge is to balance weight, food acceptability and resource utilization. Answers could be found in “bioregenerative” systems that allow astronauts to grow some of their own food. 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
