Unidentified objects, witnessed by military pilots... Extraterrestrial probes, flying through our solar system... And a potential alien home world that may be hidden in the darkness of space. Does the recent string of strange encounters and phenomena get us closer to answering the age old questions, are we alone in the universe? What tools are we using to hunt for signs of life in outer space? And is it possible that evidence of alien intelligence has actually reached planet Earth?
As we make plans to travel beyond the Moon to new worlds, how are we preparing to become human extraterrestrials? Just how will we survive this trip into the unknown? Will we be able to thrive once we get to our next galactic destination? And what will we do if we make contact with intelligent life?
The blue marble we call Earth remains in large part a mystery to the 8 billion people who live on it. How did Earth come to exist, and what are the secrets of its survival? How long will humans be able to call it “home”?
For centuries, we've been fascinated by our nearest planetary neighbor, Venus, and its shimmering appearance in our night sky.

Is Venus our evil twin--or a warning about what Earth will become in the future?
From massive asteroids and deadly bursts of radiation to microscopic alien viruses, each one of these cosmic dangers may end human civilization as we know it. Can we prepare for the inevitable calamity that may be coming our way? Or are we doomed to oblivion?
