Unusual but true: Cuban artist paints underwater

Ice cave glows in sunlight

This is the incredibly rare moment an ice cave glows gold, as the sun sits perfectly in line with its glistening walls.

The amazing images were taken at the exact minute the sun set over the entrance to the glacier in Iceland, a phenomenon only possible once or twice in a year. As a result, the walls looked as if they were on fire as they were bathed in the golden light.
