We used to think that Earth was at the center of the universe, but now we know we're not even at the center of our own galaxy. Countless wonders exist between where earth is situated and the massive black hole at the galactic center of our solar system. Within the Milky Way can be found the debris of old, dying stars fueling the birth of new stars and at the galactic center hypervelocity stars get catapulted clear beyond the Milky Way's outer rim at unimaginable speeds. Come along for a guided tour of 100,000 light-year-wide family of stars and stellar phenomena we call The Milky Way.

An exploration of Earth's cosmic neighborhood. Looking beyond the borders of our solar system, what's nearby in our galaxy? How do the other objects in our local area influence life on Earth?

Some of the world's leading physicists believe they have found startling new evidence showing the existence of universes other than our own.

Asteroids, comets, gamma ray bursts, and the sun all combine to make the Earth a dangerous place to live. NASA's top brass and other scientists are arming themselves with the latest technology to pre-empt an apocalyptic attack.

Earth may seem like the most hospitable planet in the solar system. But look again. Startling new discoveries reveal the blue planet has been plagued by more chaos and destruction than scientists once imagined.

It sounds like a Hollywood blockbuster: a deadly asteroid is on a collision course with Earth. But in reality, it's only a matter of time before a giant space rock threatens to wipe out civilization. An asteroid took out the dinosaurs sixty-five million years ago. Are we next? This episode analyzes the threat and explores the many ways--from a nuclear bomb to ingenious new technology--that experts are proposing to stop Armageddon.

Imagine a tornado so powerful, it can form a planet, or winds sweeping across a planet but blowing at 6,000 miles per hour! How about rain....made of iron? Sounds like science fiction, but this type of weather is occurring daily in our solar system.

It bursts from the sun with the power of ten thousand nuclear weapons... and when it hits our planet, it could create the largest disaster in recorded history.
