In this episode of The Atlas Obscura Podcast, we tell the story of a satellite scientist and a ship captain in search of gigantic swaths of bioluminescence that radiate up from the surface of the sea over thousands of square miles.

Our podcast is an audio guide to the world’s wondrous, awe-inspiring, strange places. In under 15 minutes, we’ll take you to an incredible site, and along the way you’ll meet some fascinating people and hear their stories. Join us daily, Monday through Thursday, to explore a new wonder with cofounder Dylan Thuras and a neighborhood of Atlas Obscura reporters.
