Secrets of the space probes. They've discovered water on other planets and snatched the actual building blocks of life from a comet's tail, photographing, drilling and even sniffing new worlds in the quest for life. But can space probes find a new Earth? Or make contact with alien life? Asteroid attack. Witness the latest discoveries in the deadly world of asteroids. Will a recently returned Japanese spacecraft become the first to bring an asteroid sample back to our planet? Learning about these huge space rocks isn't just about science, it's about survival. Total eclipse. Explore the complex movements of Earth, Moon and Sun that produce total solar eclipse--one of the most spectacular phenomena in the heavens. Then, go into deep space, where the tiny eclipses caused by planets circling distant stars may soon reveal exoplanets, perhaps in habitable zones like the Earth. Dark future of the sun.

In another five billion years, the aging star will bloat out beyond the orbit of our planet, incinerating all living things, including humans.if we're still around.
