Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - What is the potential habitability of planets in the Epsilon Eridani star system? See article.
g Abodes - Using observations from both space and Earth-based telescopes, a new planet that is only 1.6 times the radius of Earth. See article.
g Message - "If we want to find evidence for the existence of extraterrestrial civilizations, we must work out an observational strategy for detecting this evidence in order to establish the various physical quantities in which it involves,” according to the paper “Detectability of Extraterrestrial Technological Activities.” “This information must be carefully analyzed so that it is neither over-interpreted nor overlooked and can be checked by independent researchers.” Read the entire paper online. See article. Note: This paper was presented in 1992.
g Learning - NASA and the Library of Congress have established the Baruch S. Blumberg NASA-Library of Congress chair in Astrobiology at the Library’s scholarly research organization, the John W. Kluge Center in Washington. The chair is named for the late Nobel Laureate and founding director of the NASA Astrobiology Institute, Baruch “Barry” Blumberg. 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.
