Explanation: This is what the Earth looks like at night. Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth’s surface, including the seaboards of Europe, the eastern United States, and Japan. Many large cities are located near rivers or oceans so that they can exchange goods cheaply by boat. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The featured image, nicknamed Black Marble, is actually a composite of hundreds of pictures remade in 2016 from data taken by the orbiting Suomi NPP satellite.

说明: 这是地球在夜间的面貌。你能找到你最钟爱的国家或城市吗？很出乎意料的，有都市灯光作为导引，这个工作并不难。人为的灯火突显了地球表面高度开发或人口特别密集的区域，包括：欧洲沿岸、美国东岸和日本。许多大都会紧邻河流或海洋，目的是要利用低廉的船泊运输来交换货物。影像里，特别暗黑的区域则出现在南美洲、非洲、亚洲和澳洲的中部。这张昵称为“黑弹珠”的主题照片，是在2016年使用Suomi NPP卫星先前取得的数百幅影像组合重制而成。
