We once considered ourselves to be at the center of the universe — now we know that we are just a small spec in a giant cosmos. This season, The History Channel® ventures outside of our solar system in another epic exploration of the universe and its mysteries. With strikingly realistic computer re-creations, you'll feel like you've traveled to the edge of the unknown: visit strange and unfamiliar worlds in "Exoplanets," prepare for the worst in "Cosmic Collisions," and uncover the secrets of our own galaxy, "The Milky Way." And that's just the beginning . . . learn exactly what "Dark Matter" is and how it takes up 95% of the universe; take a front-row seat for the ultimate light show with "Supernovas;" and while most people have heard of black holes (which swallow all matter that they come in contact with), find out more about "White Holes" — which actually create matter.
