One day last week Roger Ebert turned is mind from film to contemplate the immensity of things: … The universe is too large for me to comprehend how large that really might be. I’ve seen those animations where Earth shrinks to a pin point, and then the sun shrinks to a pin point, and then […]
Carl Sagan was a hero to most of us who in one way or another like to watch the skies. The mellifluous-voiced, turtleneck-and-corduroy-wearing astronomer inspired my generation to care about space, about our planet, and about our future as a spacefaring civilization.

For half a century we have been searching the sky for extraterrestrial intelligence, using radio telescopes. This is on the assumption (debatable) that advanced ETs would still be communicating in the radio band. But what if they are trying to communicate with us in some other way? And what if their message to us isn’t […]

If you’re on the fence about UFOs, take a look at these collections of NASA photos and footage compiled by LunaCognita and see what you think. Most of the still photos aren’t particularly compelling, and the perfectly straight-moving objects in Earth orbit clearly appear to be satellites, space junk, or dust. But the footage of […]
