When the Earth passes by way of this particles path, these small bits of detritus enter our environment and expend, showing as blazing lights that streak throughout the sky.
Within the case of the Southern Delta Aquariids, it’s not clear which comet is the supply, nevertheless it’s believed to be 96P Machholz.
