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 - What is the potential habitability of Struve 2398, a trinary just 12 light years from Earth? See article.
g Abodes - Among the 'footprints left on Earth's climate by humans is an over-abundance of available nitrogen. Scientists are now trying to determine how this disruption in the nitrogen balance will affect the future of life on Earth. See article.
g Cosmicus - Recently, Theoretical Physicist Marcelo Gleiser, the Appleton Professor of Natural Philosophy Dartmouth College, was asked to give an opening lecture at an international conference on astrobiology, linking cosmology to the emergence of life on Earth and other planetary platforms. His conclusion: We, and any other alien creature that might exist, are products of the same laws of physics and chemistry that operate across the cosmos. 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
