这张日食合成图中的深色条纹是什么？它们是月亮边缘山脉的倒影。这张从中国厦门拍摄的中央图像显示，月球的中心正对着太阳的中心。然而，月球离地球太远，无法完全挡住整个太阳。环绕月球边缘的光被称为火环。序列两端的图像显示了穿过月球山谷的阳光。当月球从左到右移动到太阳前面时，只有月球周围的高峰才能阻挡阳光。因此，黑暗的条纹被投射、扭曲、反转和放大了月球边缘山脉的阴影。明亮的区域被称为贝利珠。2020年，只有在地球东半球狭窄地带的人们才能看到这次日环食。然而，下个月，横跨北美和南美的狭长地带将暴露在下一次日环食中。明年4月，整个北美地区都能看到日全食。开放科学：浏览天体物理学源代码库中的3000多个代码

What are those dark streaks in this composite image of a solar eclipse? They are reversed shadows of mountains at the edge of the Moon. The center image, captured from Xiamen, China, has the Moon's center directly in front of the Sun's center. The Moon, though, was too far from the Earth to completely block the entire Sun. Light that streamed around the edges of the Moon is called a ring of fire. Images at each end of the sequence show sunlight that streamed through lunar valleys. As the Moon moved further in front of the Sun, left to right, only the higher peaks on the Moon's perimeter could block sunlight. Therefore, the dark streaks are projected, distorted, reversed, and magnified shadows of mountains at the Moon's edge. Bright areas are called Baily's Beads. Only people in a narrow swath across Earth's Eastern Hemisphere were able to view this full annular solar eclipse in 2020. Next month, though, a narrow swath crossing both North and South America will be exposed to the next annular solar eclipse. And next April, a total solar eclipse will be visible across North America.
