The spectacular and magical light produced by glowworms, fireflies and luminous plankton is known as bioluminescence - light made by living creatures. But those quite familiar glows and flashes are just a tiny, easily observed fragment of a previously unexplored, mysterious realm. Sir David Attenborough will be our guide, as we venture into a world he describes as "utterly unlike our own". He and a team of the world’s leading scientists take us on a quest into the fascinating realm of living light.
