说明:你不必到美国纪念碑谷,也能看到像上面这种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的之美丽前景。孤丘是由硬岩所组成,是它们周遭的软岩被流水侵蚀后的孑遗。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侧的孤丘合称为手套,而梅里克丘就在其右方不远处。此外,还可见到自地平面开展如扇的泛绿气辉。而高挂在天空中、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几乎任何人都能够看到带状的银河。但是要捕捉夜空中的这些色彩,还是需要有一部灵敏的数位相机。

Explanation: You don't have to be at Monument Valley to see the Milky Way arcacross the sky like this -- but it helps.Only at MonumentValley USA would you see a picturesqueforeground 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 thefeaturedimage taken a month ago, the closest butte on the left and the butte to its right are known as the Mittens, whileMerrick Butte can be seen farther to the right.Green airglow fans up from the horizon. 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 almostanyone on almost any clear night when far enough from a city and surrounding bright lights,but a sensitive digital camera is needed to capture these colorsin a dark night sky.
