Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; Career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Stars -Like gluttonous piranhas, supermassive black holes in young galaxy clusters gorge on bountiful gas until little fuel is left, and then they fade away, a new study suggests. See http://www.space.com/scienceastronomy/070724_clusters_agn.html.
g Message -Dan Werthimer, director of the SERENDIP SETI program and chief scientist of SETI@home at the University of California Berkeley, predicts we’ll make first contact with an alien civilization in 50-100 years. See http://www.astroseti.org/danweng.php. Note: This article is from 2004.
g Cosmicus -There are many practical benefits to space exploration. Advances in space technology have a dramatic effect on Earth technology. Benefits range from new ergonomic solutions for people who do repetitive work to industrial medical X-ray machines. Listed below are several of these benefits. See http://spaceflight.nasa.gov/shuttle/benefits/index.html. Note: This article is from 2002.
g Learning -Here’s a neat classroom activity courtesy of DiscoverSchool.com: “Extraterrestrials.” In the activity, a digital radio message, intended to alert any intelligent life in space to the existence of intelligent life on Earth, has been electronically transmitted into space by the Arecibo radio dish in Puerto Rico. Students must ensure the message is effective by showing that the senders (humans from Earth) are capable of advanced thinking — but it must not depend on the ability of extraterrestrials to understand any Earth language.

g Imagining - Those who think aliens with wrinkled noses are an infuriatingly lazy approach to depicting the potential diversity of life in the universe will find a welcome home at Biology in Science Fiction. See http://sciencefictionbiology.blogspot.com/.
g Aftermath -How will the press handle the announcement that we’ve made contact with an etraterrestrial intelligence? See http://www.centauri-dreams.org/?p=1109.
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.
