Summary

Story summary

Stanford University researchers explain will-o’-the-wisps in wetlands arise from microlightning that ignites methane bubbles.
Experiments show tiny electrical discharges between charged bubbles produce flashes that ignite methane.
The sparks trigger methane oxidation without an external flame, offering a natural explanation for the lights.
Findings published in the Proceedings of the National Academy of Sciences (PNAS).
