Tonight’s peaceful science story follows a star from its earliest cradle to the materials that can one day become planets. We begin in dark, cold molecular clouds, where tiny fluctuations grow into dense regions. Gravity pulls inward, a protostar forms, and an accretion disk spreads like a slow cosmic record—storing angular momentum and feeding the newborn star. Inside the disk, dust grains collide, ice lines shift, and chemistry changes with distance from the heat. A calm, accurate, sleep-friendly guide through the origins of suns and worlds.
This video is created for educational purposes to explore scientific ideas in a peaceful, sleep-friendly format.
