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 youre sitting. Travel backwards in time and it mightve 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 youd 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.
