The Solar Nebula: Our 4.6-Billion-Year-Old Origin Story

Every story has a beginning. Ours starts with a cloud of dust. In this episode, Dr. Hakeem Ali-Bocas Alexander journeys back to the very dawn of our cosmic neighborhood, reading from Chapter 2 of 'Beyond the Blue Planet.'

Uncover the violent and beautiful genesis of the system we call home. Discover:

•The ancient solar nebula—a vast cloud of gas and dust that became the cradle for our Sun and planets.

•The cosmic trigger—how a nearby supernova's shockwave may have ignited the collapse that started it all.

•The great divide—why the inner solar system forged rocky worlds like Earth while the outer realms gave birth to gas giants and icy dwarfs.

•The chaotic early days—how gravitational tugs-of-war and colossal collisions sculpted the orbits we see today.

•Why this ancient history is our most valuable guidebook for discovering and understanding planets around other stars.

This is the greatest story ever told: how we came to be.
