In the city of Yeysk, Krasnodar Territory, eyewitnesses captured ships sailing in the sky over the Black Sea. Video released telegraph channel “Eysk overheard”.
In the images, you can see that two distant ships appear to be floating above the sea. This illusion is due to a rare optical phenomenon called fata morgana.
It occurs when several alternating layers of air of different densities form in the lower layers of the atmosphere, which, due to temperature differences, can produce mirror reflections. As a result of the refraction of rays as well as reflection, real-life objects give a few distorted images at or above the horizon.
This phenomenon got its name in honor of the sorceress – the character of English legends Fairy Morgana.
Before the Hubble telescope caught optical illusion in space. He photographed two spiral galaxies as if they were stuck in a collision.
