是什么创造了魔鬼塔?这个位于美国怀俄明州的非凡巨石的起源仍然存在争议,一个主要的假设认为它是一个硬化的熔岩柱,从未到达表面成为火山。在这个理论中,曾经包围密集火山颈的较轻的岩石现在已经被侵蚀掉,留下了这座引人注目的塔。被美洲原住民称为“熊小屋”和“大灰角”,密集的岩石包括已知最长的六角形石柱,有些石柱高达180多米。高高在上,银河系的中心带横跨天空。许多值得注意的天空物体都是可见的,包括管道星云的黑色条纹和塔右侧的红色泻湖星云。绿色的草地和树木排列在前景中,而云出现在塔左侧的地平线附近。与许多其他国际地标不同,登山者被允许攀登魔鬼塔。生日惊喜:APOD在你的生日上放了什么照片?(1995后)

What created Devils Tower? The origin of this extraordinary rock monolith in Wyoming, USA is still debated, with a leading hypothesis holding that it is a hardened lava plume that never reached the surface to become a volcano. In this theory, the lighter rock that once surrounded the dense volcanic neck has now eroded away, leaving the dramatic tower. Known by Native Americans by names including Bear's Lodge and Great Gray Horn, the dense rock includes the longest hexagonal columns known, some over 180-meters tall. High above, the central band of the Milky Way galaxy arches across the sky. Many notable sky objects are visible, including dark strands of the Pipe Nebula and the reddish Lagoon Nebula to the tower's right. Green grass and trees line the foreground, while clouds appear near the horizon to the tower's left. Unlike many other international landmarks, mountaineers are permitted to climb Devils Tower.
