一缕阳光
The Moon is seen passing in front of the Sun during a solar eclipse from Ross Lake, Northern Cascades National Park, Washington on Aug. 21, 2017. A total solar eclipse swept across a narrow portion of the contiguous United States from Lincoln Beach, Oregon to Charleston, South Carolina. A partial solar eclipse was visible across the entire North American continent along with parts of South America, Africa, and Europe.
This was the first total eclipse to span the U.S. since 1918, and with scientific advancements, presented a perfect opportunity to shed light on phenomena such as solar flares and coronal mass ejections.
See when and where in the United States solar eclipses will be visible in 2023 and 2024.

2017年8月21日，在华盛顿州喀斯喀特国家公园北部的罗斯湖发生日食时，月亮从太阳前面经过。一次日全食席卷了美国从俄勒冈州林肯海滩到南卡罗来纳州查尔斯顿的一小部分地区。整个北美大陆以及南美、非洲和欧洲的部分地区都可以看到日偏食。
这是自1918年以来第一次横跨美国的日全食，随着科学的进步，这为阐明太阳耀斑和日冕物质抛射等现象提供了绝佳的机会。
