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 - Many galaxies contain enormous amounts of molecular gas in small areas near their nuclei. Highly condensed molecular gas is a birthplace of lots of stars. Moreover, it is considered to closely relate to activities of galactic nuclei. Therefore, it is important to investigate the physical state and chemical properties of molecular gas at galaxy centers through observation. To obtain detailed observation data, it is best to survey the center of the Milky Way Galaxy in which our solar system exists. See article.
g Abodes - Mars Express has imaged an area to the south of the famed Valles Marineris canyon on the Red Planet, showing a wide range of tectonic and impact features. See article.
g Life - In a breakthrough effort for computational biology, the world's first complete computer model of an organism has been completed, Stanford researchers reported last week in the journal Cell. See article.
g Cosmicus - Eureka High's class of 1987 gathered this weekend for a 25-year reunion, but alumnus Paul Thompson couldn't make it; he's busy fulfilling a childhood dream. 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.
