Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - A team of scientists has succeeded in identifying one of the most complex organic molecules yet found in the interstellar medium. The findings will help astrobiologists understand the production of organic molecules in space and how these molecules could have played a role in the origin of life on Earth. See article.
g Message - The privatization of SETI has resulted in global participation in signal detection and analysis activities by a wide range of non-professionals. The SETI community welcomes this grass-roots support, every bit as much as the optical observing community honors the significant scientific contributions of the world's amateur astronomers. However, as SETI observatories spring up on college campuses and in home gardens worldwide, a need emerges for establishing rigorous signal verification protocols and stringent standards of proof. See article.
g Aftermath - Within the scientific community, the question is no longer whether extraterrestrial life exists, but if ET is smart enough to do long division — and the U.S. and other world governments already have detailed secret plans for first contact. My apologies in advanced for Popular Mechanic’s lurid title, but the reporting is sound; 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
About Me
- Rob Bignell
- I'm the owner and chief editor at Inventing Reality Editing Service, which meets the editing and proofreading needs of writers both new and published. For more than two decades, I worked as an award-winning journalist, with half of those years spent as an editor. Several of my short stories in the literary and science fiction genres have been published, and I am the author of the nonfiction “Hikes with Tykes” series, a novel "Windmill", and a collection of poetry, "Love Letters to Sophie's Mom". For seven years I worked as an English teacher or a community college journalism instructor. I hold a master's degree in English and a bachelor's in journalism and English.
