The solar system we know may seem eternal. Yet long before our Sun and planets began their elegant dance, billions of years of chaos and wreckage reigned supreme. From planets, asteroids, and moons forged from stardust, to volcanoes unleashing fiery destruction on Mars, and a cataclysmic collision that turned early Earth molten and gave birth to our Moon, this series explores the defining milestones of our Solar System.
