Un raro pilastro di luce vulcanica è apparso sopra l’Etna, creando uno spettacolo surreale nel cielo notturno. Il fenomeno, catturato in uno scatto straordinario, è dovuto alla rifrazione della luce sulle particelle emesse dal vulcano: https://fanpa.ge/GpgNM

Light Pillar over Erupting Etna (APOD: 2025 Feb 24)

Explanation: Can a lava flow extend into the sky? No, but light from the lava flow can. One effect is something quite unusual -- a volcanic light pillar. More typically, light pillars are caused by sunlight and so appear as a bright column that extends upward above a rising or setting Sun. Alternatively, other light pillars -- some quite colorful -- have been recorded above street and house lights. This light pillar, though, was illuminated by the red light emitted by the glowing magma of an erupting volcano. The volcano is Italy's Mount Etna, and the featured image was captured with a single shot during an early morning in mid-February. Freezing temperatures above the volcano's lava flow created ice-crystals either in the air above the volcano or in condensed water v***r expelled by Mount Etna. These ice crystals -- mostly flat toward the ground but fluttering -- then reflected away light from the volcano's caldera.
