Emissions from Nearby Developed Intelligent Populations
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 - The mountainous region on the far side of the Moon may be the remains of a collision with a smaller companion moon. See article.
g Message - The extent of the SETI project is by no means limited to scanning radio frequencies. SEVENDIP stands for the “Search for Extraterrestrial Visible Emissions from Nearby Developed Intelligent Populations,” an Optical SETI effort. SEVENDIP employs a 30-inch automated telescope located in Lafayette, California to scan the sky for potential signals from E.T. Since its inception in 1997, SEVENDIP has pioneered the use of optical technology to search for nanosecond time-scale pulses—pulses that could be generated by the powerful laser of a distant civilization. See article.
g Cosmicus - Astrobiology Magazine Field Research Editor Henry Bortman recently spent a week in British Columbia with scientists from the Pavilion Lake Research Project. In his fifth report he describes behind-the-scenes software that helps PLRP achieve its scientific goals. 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
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.
