It wasn’t an asteroid from the asteroid belt. It was a comet; a big frozen rock that came from a mysterious, unseen sphere of ice, rock, and primordial debris that surrounds our entire solar system: the Oort Cloud. And the unsettling part is that the Oort Cloud could possibly be filled with millions of similar frozen time bombs. One big enough could be nudged or pulled by a planet or passing star and sent on a deadly trajectory toward Earth, turning our planet into nothing more than a lifeless rock drifting through space. And now, something even bigger has been discovered emerging from this ancient graveyard of ice and rock; a mega comet so massive it dwarfs the one that ended the age of the dinosaurs. But the Oort Cloud isn’t just a distant threat; it’s a mysterious structure at the very edge of our solar system, hiding secrets that could reveal new dangers and even… life.
