在2017年8月21日,北美将会看到一个世纪第一个日全食。当月亮,太阳与地球之间穿过日食发生。尽管太阳比月球大得多,因为月亮是那么更接近我们,他们对出现在天空中的大小相同。如果月亮是充分和完全一字排开,结果是总日食。
In August, this perfect alignment—the total eclipse—will occur along a 70-mile-wide (113-km wide) line that cuts through 12 states, from Oregon and Idaho through Missouri and Illinois, and ending in South Carolina. Observers in this area will see the moon approach the sun, cover it completely so that only a bright ring appears around the moon, and then pass over. The whole process takes two or three hours. The moon will totally obscure the sun for about 2 minutes, during which time the sky becomes dark as night.
即使你不生活在一个地区,你可以看到日全食,你仍然可以体验这独一无二的活动。几乎所有的美国大陆将会看到太阳的至少70%的覆盖率在日偏食。但小心点!你需要佩戴特殊的眼镜日食和对你的相机太阳能过滤器来查看事件。在日食直视会导致眼睛的永久伤害,甚至如果你正在寻找通过望远镜。
