Summary

Story summary

Researchers identify methane ignition as the cause of will-o’-the-wisps (ignis fatuus), driven by microlightning between methane-containing microbubbles.
Earlier theories proposed cool flames from methane oxidation, but activation energy made natural ignition unlikely.
Experiments show microlightning can initiate chemical reactions, producing luminescence and heat.
The study provides a scientific explanation for ignis fatuus and calls for more swamp dynamics research.
