Today, we know black holes exist, and now scientists are trying to confirm that other holes lurk in hyperspace. Our infinite cosmos could contain a variety of "holes" such as black, white, "mini" and wormholes. White holes are the reverse of black holes; instead of matter being sucked into it, matter is ejected out. Wormholes are gateways in the fabric of space and time. Neither white holes nor wormholes have ever been found. Learn about new discoveries including, colliding binary black holes, intermediate black holes, and manufacturing mini black holes.

Ignited by the power of the atom, burning with light, heat, and wrath, stars are anything but peaceful. They collide, devour each other, and explode in enormous supernovas--the biggest explosions in the Universe. Using cutting-edge computer graphics, never-before-seen satellite images, and interviews with the world's leading astronomers, take a front row seat to the most amazing light show in the cosmos.

We are in the midst of the greatest era of space discovery. 21st century spacecraft and sophisticated imaging technology are venturing into un-chartered territory every day--and much of the extraordinary phenomenon is happing right in our own cosmic backyard. Take an exhilarating, unprecedented exploration of the seven most amazing wonders of our solar system. Our virtual tour begins with a trip to Enceladus, one of Saturn's outer moons, where icy geysers spout from its surface. Then venture to Saturn's famous rings, which contain mountain ranges that rival the Alps. Next dive into the eye of the biggest storm in the solar system--Jupiter's Great Red Spot. Soar through the Asteroid Belt, containing millions of leftover rocks from the formation of the solar system. Trek up Mount Olympus, the largest volcano, located on Mars. Have a close encounter with the searing surface of the sun, and finish the journey by exploring our home planet, Earth.

The planets of our solar system have experienced epic catastrophes throughout their long history, both raining down from outside and bubbling up from within. We'll voyage back in time to investigate the violent events that profoundly shaped the planets, including earth itself. We'll witness stunning revelations about what transformed Mars into a barren, hostile desert...The disaster that changed Venus from temperate to hellish...The impact that blew away Mercury's mantle, turning it into a planetary core...A colossal disturbance that rearranged the orbits of the gas giants...Titanic impacts on Jupiter...And how a lost moon may finally explain Saturn's rings.

Outer space is already an essential part of America's ability to fight wars. Our military depends on satellites for many things, such as communications, reconnaissance, and targeting information. But so far, no country has put weapons into space, although the U.S. and China have both shown they can shoot down satellites with ground-based missiles. If weapons do become a part of space, how will they work, how effective will they be, and what type of damage could they do? From ground-based lasers to telephone-pole-sized rods hurtling from space at two miles per second to the far out weapons of the distant future, it's time to "lock and load" for Space Wars.

The Universe is full of explosions that both create and destroy. The Chicxulub impact on the Yucatan peninsula, which may have wiped out the dinosaurs 65 million years ago, was two million times more powerful than the largest nuclear bomb ever detonated on Earth. But guess what? That's only good enough for the very bottom of the Biggest Blasts top ten list. This episode works its way up through supernova explosions and gamma ray bursts all the way to the blast that started it all--the Big Bang.

Don't try this at home! In this episode, our experts cook up ten ways you could destroy the earth, including: swallowing it with a microscopic black hole; blowing it up with anti-matter; hurling it into the Sun, and switching off gravity. This is a fun way to explore the dangerous physics of the Universe and the properties of the planet we call home.

It may seem like seem like science fiction, but the cosmos isn't just something way out there. Many times in human history, objects or forces from space have changed the course of life on earth. Many believe an asteroid played a role in the fall of the Roman Empire...and millennia earlier another asteroid might have been the "fire and brimstone" that destroyed Sodom and Gomorrah.
