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 suggests that a rocky planet twice the size of Earth and orbiting a nearby star is a diamond planet. It may be the first glimpse of a rocky world with a fundamentally different chemistry than our own planet. See article.
g Life - A New York Medical College developmental biologist whose life's work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions - that survival is based on a change's functional advantage if it is to persist. Stuart A. Newman, Ph.D., professor of cell biology and anatomy, offers an alternative model in proposing that the origination of the structural motifs of animal form were actually predictable and relatively sudden, with abrupt morphological transformations favored during the early period of animal evolution. See article.
g Message - Two new research grants are supporting projects that bleed into science fiction. The first could help identify advanced civilizations powered by massive, orbiting solar power stations. The second study will look for ways of detecting universes other than our own. 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.
