This week NASA's Astronomy Picture of the Day shared this photo of a full circle rainbow, captured over Cottesloe Beach near Perth, Western Australia.
The amazing photograph was captured from a helicopter flying between the setting sun and a rain downpour.
According to NASA, such rainbows are "observer-dependent phenomenon primarily caused by the internal reflection of sunlight by raindrops. The 84-degree diameter rainbow followed the helicopter, intact, for about 5km."
