During thunderstorms, electric discharges in the air cause trees to glow with an ultraviolet aura. You can't see it with your eyes, but researchers have finally managed to measure it & recreate it in the lab.

@coreyspowell Any sharp point in enough of an electric field will create corona. Not sure what "new thing" they have discovered ?

@Extelec @coreyspowell
I try to understand if they are talking about something significantly different to "St. Elmos Fire" that is a visible strong corona discharge known since many centuries

Espically becasue they never refer to this phenomen
