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 Abodes - Astronomers at the University of Rochester are pointing to three nearby stars they say may hold "embryonic planets" — a missing link in planet-formation theories. See article.
g Life - Unlike normal jellyfish, which drift in the ocean current, box jellyfish are active swimmers that can rapidly make 180-degree turns and deftly dart between objects. Scientists suspect that box jellyfish are such agile because one set of their 24 eyes detects objects that get in their way. See article.
g Intelligence - While many scientists have considered masculine tendencies to be barriers to health and recovery, a small study of about 50 men suggests the opposite. The man-of-steel mentality, often associated with military men and those in other high-risk occupations, can boost and speed up a guy’s recovery from a serious and/or traumatic injury possibly. See article.
g Message - Here’s a neat piece: an interview with Frank Drake, the astronomer and pioneer who flipped the "on" switch for Project Ozma, the first modern “SETI” project. See article. Note: The interview is from 2000.
g Cosmicus - Four projects that will advance key technologies to meet critical needs for NASA's mission will be led by Ames Research Center, Moffett Field, Calif. The projects are part of NASA's Innovative Partnerships Program Seed Fund that addresses technology barriers with cost-shared, joint-development programs. See article.
g Learning - Here’s something neat, courtesy of NASA: astrobiology science learning activities for afterschool.
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.
