Venture miles beneath the Earth’s crust into a realm of crushing pressure and searing heat, where Earth’s largest ecosystem thrives in total darkness. The ancient lifeforms in Earth’s deep biome are rewriting the rules of biology, forcing us to redefine the absolute limits of survival. The existence of this subterranean alien world provides a tantalising blueprint: could life also be hiding beneath the surface of other planets across the cosmos?
