Planet Erde - Satellit sieht Doppel-Regenbogen



NASA's Aqua satellite caught an arresting image of a rainbow-like optical phenomenon called a glory over the Pacific Ocean on June 20.
Glories can be seen on Earth with the naked eye when looking down upon fog or water vapor, as when climbing a mountain or looking down upon clouds from an airplane.
The phenomenon is caused by light scattered backward toward the viewer by individual water droplets, producing an oscillating pattern of colors ranging from blue to green to red to purple and back to blue again.
