英文原文:Explanation: The dark-floored, 95 kilometer wide crater Plato and sunlit peaks of the lunar Alps (Montes Alpes) are highlighted in this this sharp telescopic snapshot of the Moon's surface. While the Alps of planet Earth were uplifted over millions of years as continental plates slowly collided, the lunar Alps were likely formed by a sudden collision that created the giant impact basin known as the Mare Imbrium or Sea of Rains. The mare's generally smooth, lava-flooded floor is seen below the bordering mountain range. The prominent straight feature cutting through the mountains is the lunar Alpine Valley (Vallis Alpes). Joining the Mare Imbrium and northern Mare Frigoris (Sea of Cold) the valley extends toward the upper right, about 160 kilometers long and up to 10 kilometers wide. Of course, the large, bright lunar alpine mountain below and right of Plato crater is named Mont Blanc . Lacking an atmosphere, not to mention snow , the lunar Alps are probably not an ideal location for a winter vacation . Still, a 150 pound skier would weigh a mere 25 pounds on the Moon . 说明：在这张清晰的月球表面望远镜照片[3]中，可以看到直径95公里、底部是深色的柏拉图环形山，以及阳光照射下的月球阿尔卑斯山脉[4]（Montes Alpes）被突显出来。地球上的阿尔卑斯山脉[5]是数百万年来大陆板块缓慢碰撞隆起形成的，而月球阿尔卑斯山脉则很可能是由一次突然撞击形成的，这次碰撞造就了被称为雨海[6]（Mare Imbrium）的撞击盆地[7]巨大结构。照片中可以看到，雨海底部平坦，遍布熔岩，其下方是与之相邻的山脉，穿过山脉的显著直线特征是月球阿尔卑斯山谷[8]（Vallis Alpes）。这条山谷连接着雨海和北部的冷海（Mare Frigoris），向右上方延伸，长约160公里，宽约10公里。当然，柏拉图环形山下方右侧那座高大明亮的月球阿尔卑斯山[9]被命名为白朗峰[10]（Mont Blanc）。由于缺乏大气，更不用说雪[11]，月球阿尔卑斯山可能不是冬季度假[12]的理想地点。不过，一个体重[13]150磅的滑雪者在月球上[14]仅重25磅。
