A darkened and mysterious north polar region informally known as Mordor Macula caps this premier high-resolution portrait of Charon, Pluto’s largest moon. Captured by New Horizons near its closest approach on July 14, the image data was transmitted to Earth on September 21. The combined blue, red, and infrared data is processed to enhance colors, following variations in surface properties with a resolution of about 2.9 kilometers (1.8 miles). In fact, Charon is 1,214 kilometers (754 miles) across, about 1/10th the size of planet Earth but a whopping 1/2 the diameter of Pluto itself. That makes it the largest satellite relative to its planet in the solar system. This remarkable image of Charon’s Pluto-facing hemisphere shows a clearer view of an apparently moon-girdling belt of fractures and canyons that seems to separate smooth southern plains from varied northern terrain.

🌓 一幅美麗又神秘的圖像展示了冥王星最大衛星查龍（Charon），北極地區的陰暗部分被非正式地稱為摩多爾黑域（Mordor Macula）。這幅圖像是由新水平號（New Horizons）在2015年7月14日接近查龍的時候拍攝的，並於9月21日傳回地球。這組由藍色、紅色和紅外線數據處理而成的圖像，通過增強色彩來展示表面特性變化，解析度約為2.9公里（1.8英里）。值得一提的是，查龍直徑為1214公里（754英里），大約是地球的1/10，但卻是冥王星直徑的一半，這使得它成為相對於其母星在太陽系中最大的衛星。這幅查龍面向冥王星半球的驚人圖像清晰顯示出一條似乎環繞整個衛星的裂縫和峽谷帶，將平滑的南方平原與多樣化的北方地形分隔開來。
