月亮通常是灰色或金色的。但是微小的、可测量的颜色差异被极大地夸大了，使得这张望远镜上的、多色的月球景观在月球的完整阶段被捕捉到。人们认为，不同的颜色对应着月球表面化学组成的真正差异。蓝色表示钛含量丰富的区域，而橙色和紫色表示钛和铁含量相对较低的区域。我们所熟悉的宁静之海，即宁静海，是图片右上方的蓝色区域。在右下角85公里宽的第谷射线环形山上，白色的线条辐射穿过橙色的月球南部高地。本月早些时候发生的满月可以算作季节性蓝月亮，因为它是不同寻常的，在北方夏季（因此是南方冬季）出现的四次满月中的第三次。这张由272张图片合成的照片显示，满月总是蓝色的，但通常没有蓝到让人惊叹的程度。几乎超空间：随机APOD生成器

The Moon is normally seen in subtle shades of grey or gold. But small, measurable color differences have been greatly exaggerated to make this telescopic, multicolored, moonscape captured during the Moon's full phase. The different colors are recognized to correspond to real differences in the chemical makeup of the lunar surface. Blue hues reveal titanium rich areas while orange and purple colors show regions relatively poor in titanium and iron. The familiar Sea of Tranquility, or Mare Tranquillitatis, is the blue area toward the upper right. White lines radiate across the orange-hued southern lunar highlands from 85-kilometer wide ray-crater Tycho at bottom right. The full moon that occurred earlier this month could be counted as a seasonal blue moon because it was, unusually, the third of four full moons to occur during northern summer (and hence southern winter). The featured 272-image composite demonstrates that the full Moon is always blue, but usually not blue enough in hue to ooh. Almost Hyperspace: Random APOD Generator
