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.

This is an episode from our new podcast, It Starts With... available on Apple, Spotify and ConnectSci.
David Boldeman speaks with CSIRO marine biogeochemist Dr Elizabeth Shadwick about one of Australia’s most important long-running ocean climate observation programs, the Southern Ocean Time Series south of Tasmania.
Host David Boldeman speaks with ConnectSci science journalist Imma Perfetto about new research that has, for the first time, measured the hearing range of humpback whales in the wild.
David Boldeman is joined by science journalist Ellen Phiddian to explore a deceptively simple question: how do scientists actually know the oceans are warming?
Four and a half thousand years ago, people were already navigating the dangerous waters of the High Arctic.
