在我們的夜空中，有很多明亮的星雲和星團，這些都是與天文學家查爾斯·梅西耶（Charles Messier）有關的，因為他在18世紀編輯了著名的目錄。他的名字也被用來命名月球上兩個很大的特別的坑——梅西耶（Messier）和梅西耶A（Messier A）。這兩個坑在月球的肥沃海（Sea of Fertility）中十分顯眼，分別有15公里乘8公里和16公里乘11公里的大小。它們的形狀是因為一顆小行星斜著撞上月球所造成的，這使得坑的形狀變得彎彎曲曲。這次淺淺的撞擊還產生了兩道明亮的物質光束，向著右邊延伸，超出了畫面。這張驚人的立體圖片是從阿波羅11號（Apollo 11）任務拍攝的兩張高分辨率圖像中製作的（AS11-42-6304，AS11-42-6305），並且需要用紅藍眼鏡來觀看（左眼使用紅色）。
原文:
Many bright nebulae and star clusters in planet Earth’s sky are associated with the name of astronomer Charles Messier from his famous 18th century catalog. His name is also given to these two large and remarkable craters on the Moon. Standouts in the dark, smooth lunar Sea of Fertility or Mare Fecunditatis, Messier (left) and Messier A have dimensions of 15 by 8 and 16 by 11 kilometers respectively. Their elongated shapes are explained by the extremely shallow-angle trajectory followed by an impactor, moving left to right, that gouged out the craters. The shallow impact also resulted in two bright rays of material extending along the surface to the right, beyond the picture. Intended to be viewed with red/blue glasses (red for the left eye), this striking stereo picture of the crater pair was recently created from high resolution scans of two images (AS11-42-6304, AS11-42-6305) taken during the Apollo 11 mission to the Moon.
