这就是夜晚的地球。你能找到你最喜欢的国家或城市吗？令人惊讶的是，城市灯光使这项任务变得相当可行。人造灯光突出了地球表面特别发达或人口稠密的区域，包括欧洲的沿海地区、美国东部和日本。许多大城市位于河流或海洋附近，以便能够通过船只廉价地交换货物。特别黑暗的区域包括南美洲、非洲、亚洲和澳大利亚的中部地区。这幅精选图像，昵称为“黑色大理石”，实际上是从2016年由在轨的Suomi NPP卫星拍摄的数据中重新制作的数百张图片的合成图。

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.
