A space probe belonging to the European Space Agency has captured the first image of a “glory” occurring on a planet besides Earth. According to Gizmodo, the glory—a rainbowlike optical phenomenon—was observed on Venus. The effect takes place when sunlight shines on cloud droplets that scatter the light into a series of colorful rings. In the case of Earth, droplets are composed of water, while Venus's clouds contain sulfuric acid. However, scientists say sulfuric acid alone could not create the phenomenon because past observations have shown the planet's clouds don't reflect light, but rather swallow it up, leading scientists to believe there is still an unidentified substance that helps compose the clouds.
