Information about this video
Consider the spot where you're sitting. Travel backwards in time and it might've been submerged at the bottom of a shallow sea, buried under miles of rock or floating through a molten landscape. But go back about 4.6 billion years, and you'd be in the middle of an enormous cloud of dust and gas orbiting a newborn star. What exactly is this cosmic dust? Lorin Matthews investigates. [Directed by Frederic Siegel (Team Tumult), narrated by Addison Anderson, music by Alon Peretz].
