終結者之月陰影月景
Terminator Moon: A Moonscape of Shadows

這個月球有什麼不同？是終結者。在這張特寫圖片中，你無法直接看到任何終結者--那條劃分白天與黑夜的界線。這是因為專題圖片是滿月上許多近終結者月帶的數字合成。 終結者區域顯示的陰影最長、最突出--陰影的對比度和長度使平面照片呈現出三維效果。這些疊加影像是 4 月初用兩週時間拍攝的。 月球上的許多環形山都很顯眼，因為它們都向右投下了陰影。該影像以圖形細節顯示，被稱為 "maria "的較暗區域不僅比月球其他部分更暗，而且更平坦。 Dial-A-Moon：查詢您今年生日的月相
原文：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.
