NEW YORK: It appears like the sky of an alien planet, or a portent for the coming apocalypse, but this photo is truly a day and evening composite—two photos taken in the identical spot along the coast of Östersund, Sweden, roughly ten hours apart.
Astrophotographer Göran Strand captured both photos on April 1st. What makes the composite so outstanding are the doppelgänger ice halos surrounding the sun and the moon. According to NASA, the radius of these halos is determined by the hexagonal geometry of atmospheric ice crystals, and by the reflection and refraction of light.
