COTTESLOE BEACH, Australia – Have you ever seen a full circle rainbow before?
Most people see rainbows from the ground, which makes them look like an arch. But when you see a rainbow from the air, you can see it's actually a full circle.
Earlier this week NASA posted this photo, taken over Cottesloe Beach, Australia, as the Astronomy Picture of the Day. The caption says it was taken from a helicopter that was flying between a downpour and a setting sun.
