Organic compounds with unexpected complexity throughout the universe and what Frank Drake says we should tell ETI
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 - New research indicates that temperatures in the Atlantic Ocean during the greenhouse climate of the Late Cretaceous were influenced by circulation in the deep ocean. The study could help astrobiologists understand how modern climate change could affect the future of our planet. See article.
g Life - Astronomers have discovered organic compounds with unexpected complexity throughout the universe. The findings could have implications in understanding how and where life can originate from organic precursors. See article.
g Message - "If you're sending a message to extraterrestrials, what you want to send is what's special about us and our planet — what is unusual," according to SETI astronomer Frank Drake. 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
