Explanation: Anchored in the vast lava flows of the Moon's Oceanus Procellarum lies the Aristarchus Plateau. The bright impact crater at the corner of the plateau is Aristarchus, a young crater 42 kilometers wide and 3 kilometers deep. Only slightly smaller, lava flooded Herodotus crater is above and to the left. A valley or rille feature likely carved by rapidly flowing lava or a collapsed lava tunnel, Vallis Schroteri begins just to the right of Herodotus and winds across the plateau for about 160 kilometers, eventually turning toward the top of the picture. Aristarchus Plateau itself is like a rectangular island about 200 kilometers across, raised up to 2 kilometers or so above the smooth surface of the lunar Ocean of Storms. Recorded from a backyard observatory in Buffalo, New York, the contrast of light-colored ejecta around Aristarchus with surrounding dark, smooth, lava flooded surfaces suggests more familiar snowy scenes of planet Earth.

说明：爱利斯塔克斯台地位于月球上暴风海的广阔熔岩内。台地角落明亮的撞击陨石坑就是爱利斯塔克斯，一个年轻的环形山，宽42公里深3公里。而形状较小，几乎被熔岩填满的西罗多德环形山位于左上方。迅速流经的熔岩或是倒塌的熔岩隧道形成里一条类似峡谷的沟纹状结构，这条名为夏洛特利峽谷开始于西罗多德右侧，在台地上穿过了160公里，最终折向影像上方。爱利斯塔克斯台地本身就像一个大小约200公里的矩形岛屿，在平坦的月球暴风海表面突出大约2公里的高度。这张影像拍摄于纽约布法罗的一个后院观测台，爱利斯塔克斯周围颜色较浅的火山喷出物与外围颜色较暗、平坦的熔岩表面形成了鲜明的对比，这与地球上出现雪景有些类似。
