This night was so serene you could see Orion rise downwards. The unusual spectacle was captured in this single-exposure image, featuring a deep sky around the famous constellation of Orion that appeared both above — and reflected in — a peaceful lake in the Gyirong Valley of Tibet, China. Taken last year at this time, the three belt stars of Orion can be seen lined up almost vertically above and below the Himalayan Mountains. The complex Orion Nebula can be seen to the belt stars’ right, while the red-glowing circular structure surrounding Orion is Barnard’s Loop. Also, the bright red star Betelgeuse is doubly visible on the image left, while bright blue Rigel appears twice on the image right. Familiar Orion is becoming increasingly visible as Winter (Summer) descends on the Northern (Southern) hemisphere. Follow APOD on: Facebook, Google Plus, or Twitter

今夜的景象格外寧靜，可以清晰地看到獵戶座向下升起。這個不尋常的光景在這張單次曝光的圖像中被捕捉到，畫面裡環繞著著名的獵戶座星座，並在一個平靜的湖泊中反射出來，這個地方位於中國西藏的吉隆谷。這張照片是在去年此時拍攝的，獵戶座的三顆帶星幾乎垂直地排列在喜馬拉雅山脈的上下側。帶星的右側可以看到複雜的獵戶星雲，而圍繞獵戶座的紅色環形結構是巴納德環。圖像左邊的亮紅星貝etarise也呈現出雙重影像，而亮藍星瑞格爾則在右側出現兩次。隨著北半球的冬季（南半球的夏季）逐漸降臨，熟悉的獵戶座變得愈加明顯。
