Get out your red/blue glasses and gaze across Ceres at mysterious mountain Ahuna Mons. Shown in a 3D anaglyph perspective view, the mosaicked image data was captured in December of 2015, taken from the Dawn spacecraft’s low-altitude mapping orbit about 385 kilometers above the surface of the dwarf planet. A remarkable dome-shaped feature on Ceres, with steep, smooth sides Ahuna Mons is about 20 kilometers (12 miles) in diameter at its base, rising on average 4 kilometers to a flattened summit. Similar in size to mountains found on planet Earth, no other Cerean surface feature is so tall and well-defined. It is not known what process shaped the lonely Ahuna Mons, or if the bright material streaking its steepest side is the same material responsible for Ceres’ famous bright spots.

佩戴紅藍眼鏡,凝視神秘的阿胡納山(Ahuna Mons)。這幅3D立體視覺的馬賽克影像數據是由「黎明號」(Dawn)太空船於2015年12月在距離矮行星谷神星(Ceres)表面385公里的低軌道映射拍攝而成。
阿胡納山是一個顯著的圓頂形特徵,擁有陡峭且光滑的邊緣,其基底直徑約20公里(12英里),平均高度為4公里,頂部扁平。它的大小類似於地球上的山脈,然而沒有其他谷神星的地表特徵如此之高且清晰。
目前尚不清楚是什麼過程塑造了孤獨的阿胡納山,或是它陡峭一側的亮色物質是否與谷神星著名的亮點有關。
