How radiation from space can damage life on Earth
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 the nearby star system 44 Draconis AB? See article.
g Life - A new study is providing information about how radiation from space can damage life on Earth, and shows that a short gamma ray burst would be more significant than a longer gamma ray bust. If one of these bursts of energy occurred nearby, it could have lasting effects on Earth's surface and oceans. See article.
g Cosmicus - Measurements from NASA's Terra spacecraft have been used to improve the most complete digital topographic map of Earth. 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
