The world-renowned biologist E.O. Wilson shares his thoughts about alien life, what it may look like, and how evolutionary forces would affect its development.
One of the folks at work discovered this amazing video; a Norwegian skydiver captured the “dark flight” of a meteor on his helmet-cam. Apparently a first, the dark flight is the period of time in between a meteor slowing down as it enters the outer atmosphere (when you see the bright streak across the sky) and when it impacts earth’s surface (more here on Wikipedia…)
UPDATE: looks like this might not have been a meteor after all :(
