Explore The Edges Of The Unknown 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, History 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.
