Shanghai Institute of Optics and Fine Mechanics successfully produced "quasi-spherical lightning," revealing its electromagnetic soliton nature.

On April 16th, according to the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, the team of Song Liwei, Tian Ye, and Li Ruxin from the National Key Laboratory of Super Intense Laser Science and Technology at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, successfully generated and stably captured for the first time under laboratory conditions spherical light emitting bodies with a scale of nearly millimeters and a lifetime of microseconds. It was confirmed that the nature of these bodies is electromagnetic solitary waves, providing decisive experimental evidence for unraveling the mystery of ball lightning. The related research results were published under the title "Ball-lightning-like relativistic terahertz solitons" in the international academic journal "Nature Photonics."
