说明: 你不必到美国的纪念碑谷，也能看到银河横过天际的景观，然而这片地景的确有加分效果。不过，只有在纪念碑谷，才能见到包括这些称为孤丘的标誌性石峰在内之美丽前景。孤丘由硬岩所组成，是它周遭的软岩被流水侵蚀掉后的孑遗。在这张摄于2012年的主题影像里，左侧最靠近我们的孤丘及其右方的石柱合称为手套，而梅里克丘就在其右方不远处。而高挂在天空中、稍带着弥漫辉光的带状结构，则是我们螺旋状银河系的中央盘面。只要在清朗的夜晚，远离城市或周围的明亮光源，都能够看到带状的银河。

Explanation: You don't have to be at Monument Valley to see the Milky Way arch across the sky like this -- but it helps.Only at Monument Valley USA would you see a picturesque foreground that includes these iconic rock peaks called buttes.Buttes are composed of hard rock left behind after waterhas eroded away the surrounding soft rock. In the featured image taken in 2012, the closest butte on the left and the butte to its right are known as the Mittens, while Merrick Butte can be seen just further to the right.High overhead stretches a band of diffuse light that is the central disk of our spiral Milky Way Galaxy.The band of the Milky Way can be spotted by almost anyone on almost any clear night when far enough from a city and surrounding bright lights.
