这个月球有什么不同？是终结者。在这张特色图片中，你无法直接看到任何明暗分界线——白昼与黑夜的分界线。这是因为这张特色图像是满月上许多接近黄昏的月球条纹的数字合成图。终结者区域显示了最长和最突出的阴影——阴影，通过它们的对比度和长度，使平面照片看起来像三维的。这些叠加图像是在4月初的两周内拍摄的。月球上的许多环形山都很突出，因为它们都向右投下阴影。这幅图像以图形的细节显示，被称为玛丽亚的较暗的区域不仅比月球的其他部分更暗，而且也更平坦。拨月：找出你今年生日时的月相

What's different about this Moon? It's the terminators. In the featured image, you can't directly see any terminator -- the line that divides the light of day from the dark of night. That's because the featured image is a digital composite of many near-terminator lunar strips over a full Moon. Terminator regions show the longest and most prominent shadows -- shadows which, by their contrast and length, allow a flat photograph to appear three-dimensional. The overlay images were taken over two weeks in early April. Many of the Moon's craters stand out because of the shadows they all cast to the right. The image shows in graphic detail that the darker regions known as maria are not just darker than the rest of the Moon -- they are also flatter.
