"Stunning Image Captures Rare Green Flash from Venus"

Photographer captures rare green flash from Venus in the night sky above Sweden, attributed to the cold atmosphere and sharp gradient in air temperatures acting like a prism. The phenomenon, more common at sea when the Sun is low on a clear horizon, lasted about a second and has gone viral on social media. Similar green flashes are emitted by the Sun when it rises above the horizon due to refraction, where the bending of light causes it to change speed as it passes from one medium to another.
