SOLVED: The Swamp Lights Were Real

For 400 years, people reported eerie blue lights dancing over marshes, which science often dismissed as folklore. Now, a stunning new paper from Stanford scientists proves the lights were real. The cause is stranger than any ghost story and connects directly to a topic from our main season. We explain the phenomenon behind these “cool flames” and explore why the last major sighting was nearly a century ago.
