## Resource

We travel nearly ten kilometres beneath the surface of our own planet to explore one of the most extraordinary discoveries in modern science. For decades, the search for extraterrestrial life has focused on distant planets and far-off stars. But some of the most compelling clues may be hiding in the deepest trenches of Earth’s oceans. In total darkness, under crushing pressure and without any sunlight, scientists have discovered thriving ecosystems powered not by light, but by chemistry. Host David Boldeman and ConnectSci journalist Evrim Yazgin unpack how these deep-sea organisms survive using chemosynthesis, breaking down chemicals like hydrogen instead of relying on photosynthesis.
