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 - A new study suggests that meteorites and their parent asteroids are the most-likely sources of water on Earth. Understanding if and how volatile elements were delivered to the early Earth is important in determining the origins of water and life on our planet. See article.
g Life - Not long after sunrise, these endangered seahorses in Broome, Australia, start slow dancing to demonstrate their attraction in a graceful courtship ritual – and up to three days later, they’re still going strong. See article.
g Cosmicus - A six-member crew has been selected for participation in a simulated Mars mission that will help determine the best way to keep astronauts nourished during long duration missions to Mars or the Moon. 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
