New Zealand's Underground Galaxy Made of Glowing Worms Will Blow Your Mind

Added: 2026-05-05

[00:00:00]Did you know there's an underground galaxy in New Zealand that's actually made of millions of tiny worms? Deep beneath the earth in Waitomo Caves, glowworms create a bioluminescent starry sky that rivals the real Milky Way above ground. These aren't actually worms at all. They're baby fungus gnats found nowhere else on earth. Each tiny larva hangs silk [music] threads like fishing lines in the pitch black darkness, then produces a blue green glow through a chemical reaction in their bodies.

[00:00:25]They're basically living light bulbs trying to catch dinner. The Maori people believed these lights were fallen stars trapped underground. And honestly, when you glide silently through the underground rivers on a boat tour, it's easy to see why. You have to stay completely quiet or you'll disturb the glowworms and they'll turn off their lights. Each glowworm only produces light equal to a single match, but millions together create an otherworldly galaxy [music] effect. These caves formed over 30 million years ago and maintain perfect conditions year round for this incredible natural light show that puts any planetarium to shame.
