The ultimate alternate "life" style. Alien life may be a lot closer to home than you thought in a shadow biosphere.
The recent report of the ubiquity of extrasolar planets coupled with the fact that it bodes well for searches for life friendly Earth twins, brought me back to my reading of Carl Sagan's 1966 Intelligent Life In The Universe and later article in Sky & Telescope where he came up with a remarkable number in favor of such.
Back in 1962, a Zambian teacher vowed that his country would beat America as the first country to put a man on the moon, and then they would go on to Mars. Unfortunately, his dream never came to fruition. The Zambians worked hard though. His "astronauts" rolled down hills in barrels to get used to traveling through space. They practiced walking on their hands, as their leader - Edward Makuka Nkoloso - assured them that was the only way to get around on the moon. "My spacemen are ready, but we...

A candid moment with Frank Drake, the mind behind the Drake equation and a founder of the search for extra terrestrial intelligence.
A very visual description of the Drake Equation, its importance to the SETI program and a thought or two as to what it means.
An animated explanation of the Drake Equation, which calculates the number of intelligent, communicable civilizations in the galaxy. Voice-over by Carl Sagan from the Cosmos clip that is already posted here.
GRRZRRZRRZRRZRRZBOOM! If you're facing a zombie apocalypse, or more run-of-the-mill zombie massacre, grab the first commercially available chainsaw bayonet on a rifle built specifically for zombie slaying - the DoubleStar Zombie-X-AK-47. No price yet, but its less fancy DSC Zombie Slayer predecessor sells for $1,249.99, so expect the Zombie-X to be a bit pricier.
I read in the Economist about a new study that reveals that our galaxy - not even the entire universe - should be colonized by now. This paper profoundly reaffirms the conundrum that is the Fermi Paradox, an observational problem that is sometimes referred to as the Great Silence.
A six-year survey of millions of stars in the Milky Way found that nearly every star has orbiting planets. This means:
The Mars rover Spirit's entire five-year mission, in less than three minutes. It took almost 2000 days for the defunct Spirit rover to travel 4.8 miles across the surface of Mars, but you can re-live its entire journey in 3,418 frames. The ending is a tear-jerker.
In my early life I was deeply impacted by the work of physician and psychoanalyst John C. Lilly. I still have my dog-eared copies of The Mind of the Dolphin (1967) and Programming and Metaprogramming in the Human Biocomputer (1968). Lilly's work, with dolphins and the development of the sensory deprivation tank, has formed the basis of movies, music and television productions.
