Investigate the theories surrounding cosmic dust bunnies and discover how the tiny particles could hold the key to the formation of life on Earth.

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.
