Center skyscraper, which is being constructed in Russia’s second-largest city.The ring of colour is so large, the worker had to pan the camera to capture its full circumference.

As the footage pans over the continuous circle of the rainbow, it’s almost hard to believe your eyes – but, while it may be a remarkable sight, the phenomenon is not entirely uncommon, as long as you have the right vantage point.

Seeing a ‘full circle rainbow’ requires the right sky conditions and the right viewing angle, typically from high above the ground, so these natural wonders are usually only seen by pilots.

When sunlight and raindrops combine to make a rainbow, they can make a whole circle of light in the sky. But it’s a very rare sight. Sky conditions have to be just right for this, and even if they are, the bottom part of a full-circle rainbow is usually blocked by your horizon. That’s why we see rainbows not as circles, but as arcs across our sky.
