This week’s Image of the Week is taken from a recent Journal of Physics D: Applied Physics article using nanosecond photography to investigate metre-scale negative laboratory discharges.
The study of laboratory discharges suggests there are similarities between such discharges and high-altitude sprites, and that they may be the result of the same underlying physical phenomena.
