Mention rainbows, and the image that comes to mind is that of a beautiful translucent arc of bright colors bending towards the horizon. But in a recent image captured by Italian astrophotographer Marcella Giulia Pace and shared by NASA on March 11, 2022, the rainbow is turned around — making it appear like it is smiling! Magical as it sounds, the reason for the stunning phenomenon, called a circumzenithal arc, is rooted in science.

Luna E3년 이상Wow it was fun learning the physics of how rainbows form like rainbows form when the sun's white light comes in contact with raindrops and refracts into the gorgeous bright color bands we are accustomed to seeing. Red has the longest wavelength and bends the least. It always appears at the rainbow's outer ring. Violet, which boasts the shortest wavelength, curves the most, ending up as the innermost color. Rainbows form full circles but are only visible as semicircles from the ground because the horizon cuts off the other half.
