Pictured here, a full-circle rainbow was captured over the Lofoten Islands of Norway in September by a drone passing through a rain shower.
An observer-dependent phenomenon primarily caused by the internal reflection of sunlight by raindrops, the rainbow has a full diameter of 84 degrees.
The Sun is in the exact opposite direction from the rainbow's center. As a bonus, a second rainbow that was more faint and color-reversed was visible outside the first.
