超级月华

英文原文:Explanation: 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 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 color diffraction effects that can be easily seen with the unaided eye. The featured image of a lunar corona was captured around last week's full Super Moon from near Knight's Ferry , California , USA . To the right of the full Moon is the giant orange star Botein . Similar coronae that form around the Sun are typically harder to see because of the Sun's great brightness. 说明: 月亮周围那些色彩缤纷的环是什么?这是一种月华[2]现象。 当通过薄云观察月亮时,有时会出现这样的环状现象。 这种现像[3]是由光线在云层中间[4](虽然云层本身大部分是透明的)大小相近的水滴周围发生绕射[5]而形成的。 由于不同颜色的光具有不同的波长[6],因此每种颜色光绕射的方式也不同。月华[7]是少数几种用肉眼即可轻松观测到的彩色 绕射[8]现象之一。 这张主题图像[9]展示了一个月华,拍摄于上周的满月超级月亮[10]附近,地点是在美国[11]加州[12]的奈特斯费里 (Knight's Ferry)[13]。在满月[14]右侧是巨大的橙色恒星博泰因星 Botein[15]。 由于太阳亮度极高,围绕太阳形成的类似日冕通常更难观测[16]到。
