What are those colorful rings around the Moon? A corona. Rings like this will sometimes appear when the Moon is seen through thin clouds. The effect is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar Coronae are one of the few quantum mechanical color effects that can be easily seen with the unaided eye. The featured lunar corona was captured around a Strawberry Moon on June 2 from La Plata, Argentina. Similar coronae that form around the Sun are typically harder to see because of the Sun’s great brightness. Huzzah: Philae lander phones home!
中文翻譯:
🌕✨ 你見過圍繞月亮的彩色光環嗎？這叫做「月亮冠」(lunar corona)。當月亮穿過薄雲時，這種效果就會出現。這是由於光在個別、大小相似的水滴周圍發生的量子力學繞射（diffraction）造成的。由於不同顏色的光有不同的波長，每種顏色的光繞射程度也不同。🔍
這個月亮冠是於6月2日的草莓月（Strawberry Moon）從阿根廷拉普拉塔（La Plata）拍攝的。相比之下，圍繞太陽的光環通常更難以肉眼觀察，因為太陽的亮度太高了。🌈🌌
