Asteroids: Spark of Life? #S53E01
Imagine a time when Earth was a molten, volcanic wasteland, heavily bombarded by colossal asteroids. We’ve long feared these cosmic impacts as destroyers of life, but what if they were the key to our very existence? Explore a revolutionary theory suggesting that these violent collisions provided the essential ingredients – water, minerals, and energy – needed for life to ignite on our planet. Discover how scientists are unearthing evidence from lunar rocks and ancient impact craters, revealing that the very objects known for extinguishing life might have actually sparked it.
Episode 1 of Season 53 from NOVA — available to stream in HD on any device.
