Behold the sun and all of it's glory. Learn all things about the sun ranging from its beginning to its death. Also learn about how stars work in general and MUCH MUCH more.

Visit the planet most like Earth. There is a discussion of what life on Mars would be like and about the life forms that could've evolved there.

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. Watch and investigate bizarre, and terrifying apocalyptic scenarios and the ways that scientists are racing against the clock to develop technology to defend our planet.

Jupiter poses many questions about our solar system. It is a powerful planet of gas whose flowing colors and spots are beautiful, but contain violent storms and jet streams. A mini solar system of over sixty moons rotate around Jupiter--a half billion miles from earth. Could one of these moons contain life under its icy crust?

The moon has comforted man for thousands of years. It's been everything from a god to a compass, and the only cosmic body human beings have ever visited.

NASA is planning to build a permanent outpost there. Discover how the moon came to be--if you don't already know, you will be astounded.

Take a high performance ride through the formation of the third planet from the Sun, Earth...

A survivor of one of the most violent "neighborhoods" in the Universe, learn how Earth was created and discover what creatures hold clues to how life began. What evil forces threaten the demise of Earth? Complex and controversial, this is the scientific detective story of all time.

Examining Mercury and Venus. Included: exploring how the damages they've suffered from cosmic collisions and acid rain may serve as a warning for Earth.

Are the rings of Saturn a real celestial phenomenon or merely a cosmic Illusion? Technology allows the experts to get closer to the furthest planet visible to the naked eye. Old questions are answered and new ones arise. Does Saturn hold the key to Earth's weather and will one of its moons supply us with all the oil we'll ever need?

Our galaxy is one of hundreds of billions in the universe. View of universe through the Hubble telescope and go back almost all the way to the Big Bang.

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.

Take a tour of the cosmic hot zones--black holes, galaxy mergers, gamma ray bursts and magnetars. Super black holes can literally lasso Earth out of the solar system. A clash between two galaxies can result in a ritual called galactic cannibalism. Magnetars are a cosmic magnetic force so strong it could wipe out data on every credit card.

Are we alone? SETI--the Search for Extraterrestrial Intelligence--is a privately funded project using radio telescopes and optical telescopes to scan the stars for signals.

The universe began with a massive expansion, billions and billions of years ago, and it continues to expand with every passing second. The idea that the universe, and man's very existence, began with a "Big Bang" is no longer a topic of debate among most scientists--it is essentially taken as fact.
