A rare photo from Italy shows a unique fan-shaped rainbow. Scientists explain the light phenomenon as anticrepuscular rays.
A unique photograph shows a strange rainbow in the sky. This rainbow does not form a full circle. It appears only as a sunlit fan shape.
Also, this image features a major visual trick. The sun seems to sit in front of the hills. However, the sun is actually located behind the viewer.
Next, experts explain how rainbows work. Sunlight must shine from behind you to create a rainbow. The light reflects off falling rain droplets.
Meanwhile, this specific scene involves a different process. Gaps in the clouds near the setting sun create this effect. These gaps allow rays to cross the whole sky.
After that, the light rays seem to meet in front of the observer. People call this rare sight anticrepuscular rays. They create a beautiful fan in the air.
Then, a local resident spotted this event in Presenzano, Italy. The person noticed the strange colors while hanging up laundry last week. They used a phone to record the moment.
Still, the sight surprised many observers. It looks like a reverse rainbow at first glance. Science explains the position of the light clearly.
Finally, the image reminds us to watch the sky. Unusual light patterns happen often near sunset. Nature creates amazing views for those who look up.
