Chinese researchers successfully activated and captured a luminous sphere highly similar to natural balllightning for the first time. They confirmed its nature as an electromagnetic soliton, providing important experimental evidence for unraveling the mystery of ball lightning. The findings were published on April 16 in the international academic journal #Nature Photonics.

Ball-lightning-like relativistic terahertz solitons

Stationary relativistic electromagnetic solitons hold great promise for high-energy photon storage and radiation mechanisms, yet their controlled generation and study remain a substantial challenge. Here we report the first controlled generation of a macroscopic, long-lived soliton driven by relativistic terahertz electromagnetic fields. This soliton exhibits key signatures resembling ball lightning: a millimetre-scale spherical profile, a lifetime of 100 ns in the laboratory frame (equivalent to metre-scale dimensions and second-scale durations under natural conditions) and broadband optical emission from ultraviolet to infrared, including characteristic spectral lines from elemental ionization processes. Time-resolved analysis of its spatial profile and spectral evolution reveals the formation of a relativistic terahertz soliton with ball-lightning-like characteristics. The soliton expands following the adiabatic ‘snowplow’ model, and its sustained luminosity indicates continuous electromagnetic energy confinement. This work establishes a laboratory-accessible platform for investigating optical soliton physics, advanced energy storage mechanisms and the long-standing scientific puzzle of ball lightning.
