昨晚的蓝月亮确实可以看到一抹蓝色。据 中国国家天文 解释，高层大气存在一个钱波斯吸收带，中心波长600nm，所以透过它的光整体偏蓝了。

这种蓝色，是由地球大气的结构引起的，低层的稠密大气会阻挡蓝光，透过红光，这就是被遮掩的月面呈现红色的原因，而高层大气则不同，其中的臭氧会吸收红光，
透过蓝光，所以在地球本影的核心区域以外，可以见到一个模糊的蓝色边缘。

Abstract


Irradiance and color during the total lunar eclipses of 2007 and 2008 are simulated using a ray tracing model that includes refraction, scattering by molecules, and observed or climatological distributions of aerosols, ozone, clouds, and topography around the terminator. Central portions of the umbra appear deep red for almost all eclipses due to preferential removal of short wavelengths in the spectrum of sunlight by scattering in the lower troposphere. The fringe of the umbra appears turquoise or blue due to selective removal of wavelengths around 600 nm by the Chappuis absorption bands of ozone in the stratosphere. Asymmetric distributions of clouds and aerosols, particularly for the 2008 eclipse, produce minimum calculated irradiance up to 17 arc min from the umbra center, while high ozone content over the arctic makes the northern edge of the umbra deepest blue.
