Nikolay Fomichev, an amateur astronomer and senior lecturer at P. G. Demidov Yaroslavl State University (YarSU), previously explained the nature of this phenomenon. According to him, light pillars resemble solar halos and occur in frosty weather when ice crystals form in the atmosphere.

These crystals refract light from the sun or artificial sources, creating vertical luminous columns. If several pillars are visible in the sky, their sources are most often streetlights or other lighting fixtures.
