A Nasa shared this Monday (24) a photo in which Lights reflected by the washing of a volcano paint the sky of Mount Etna, Italy, in Red.
“Normally, pillars of light are caused by the sun’s rays and appear as a bright column that extends above the rising or west sun,” the agency described in its project (astronomical image of the day in Portuguese).
The record made in early February shows a beam of red light by taking the sky over a morning in Italy.
According to NASA, the phenomenon happened because cold temperatures above the lava flow formed ice crystals over the volcano, causing red light to be reflected in the sky.
In the Astronomy Picture of The Day project, the US agency selects an image a day to portray an extraordinary scene related to space-like one in the sky and crossing the sky and disappearing behind a hill.
