This shadowy landscape of majestic mountains and icy plains stretches toward the horizon of a small, distant world. It was captured from a range of about 18,000 kilometers when New Horizons looked back toward Pluto, 15 minutes after the spacecraft’s closest approach on July 14. The dramatic, low-angle, near-twilight scene follows rugged mountains still popularly known as Norgay Montes from foreground left, and Hillary Montes along the horizon, giving way to smooth Sputnik Planum at right. Layers of Pluto’s tenuous atmosphere are also revealed in the backlit view. With a strangely familiar appearance, the frigid terrain likely includes ices of nitrogen and carbon monoxide with water-ice mountains rising up to 3,500 meters (11,000 feet). That’s comparable in height to the majestic mountains of planet Earth. This Plutonian landscape is 380 kilometers (230 miles) across.

這片陰暗的壯麗山脈與冰冷的平原延伸至小小的遙遠世界的地平線。這幅畫面是在2015年7月14日，當新視野號（New Horizons）太空船最接近冥王星後15分鐘，從約18,000公里的距離拍攝下來的。這幅戲劇性的低角度、接近黃昏的場景展示了粗獷的山脈，前景左側是俗稱的諾基山脈（Norgay Montes），而地平線上是希拉里山脈（Hillary Montes），右側則是平滑的斯普特尼克平原（Sputnik Planum）。在背光的視野中，冥王星稀薄的氣氛層也暴露了出來。這片冰冷的地形看起來異常熟悉，可能包括氮氣和一氧化碳冰，水冰山脈的高度可達3,500米（11,000英尺），這與地球上壯麗的山脈相當。這片冥王星的景觀寬380公里（230英里）。
