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 - In an exclusive podcast for astrobio.net, Dr. David Grinspoon, astrobiology curator at the Denver Museum of Nature & Science, discusses our violent Earth. He explains why earthquakes, severe weather, and other aspects of the dynamic environment may be necessary for life to exist. See article.
g Life - Researchers have demonstrated that flatworms are able to regenerate their excretory system from scratch. The findings could provide clues about the evolutionary origin of mammalian kidneys and the processes behind organ maintenance and regeneration. See article.
g Message - The Center for Astronomy Signal Processing and Electronics Research, or CASPER is a research group at UC Berkeley working on improving the design of radio astronomy instrumentation, including SETI instruments. 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
