我们的月球并没有这么大的陨石坑。地球的月亮Luna也不会自然地呈现出这种尖刺的纹理，它的颜色更加微妙。但这种数字创作是基于现实的。这张特色图像是由美国宇航局月球轨道激光高度计（LOLA）任务拍摄的良好月球图像和表面高度数据的数字合成而成的，然后为了便于理解而进行了夸大。例如，数字增强的图像突出了月球高地，更清晰地显示了月球在其46亿年的历史中所经历的巨大撞击。黑暗的区域被称为海陆，陨石坑较少，曾经是熔岩的海洋。此外，图像的颜色，虽然基于月球的真实构成，但被改变和夸张。在这里，蓝色色调表示富含铁的区域，而橙色表示铝的略微过剩。尽管数十亿年来月球一直向地球展示同一面，但现代技术使人类能够更多地了解月球，以及它如何影响地球。

Our Moon doesn't really have craters this big. Earth's Moon, Luna, also doesn't naturally show this spikey texture, and its colors are more subtle. But this digital creation is based on reality. The featured image is a digital composite of a good Moon image and surface height data taken from NASA's Lunar Orbiter Laser Altimeter (LOLA) mission -- and then exaggerated for educational understanding. The digital enhancements, for example, accentuate lunar highlands and show more clearly craters that illustrate the tremendous bombardment our Moon has been through during its 4.6-billion-year history. The dark areas, called maria, have fewer craters and were once seas of molten lava. Additionally, the image colors, although based on the moon's real composition, are changed and exaggerated. Here, a blue hue indicates a region that is iron rich, while orange indicates a slight excess of aluminum. Although the Moon has shown the same side to the Earth for billions of years, modern technology is allowing humanity to learn much more about it -- and how it affects the Earth.
