在夜空中，有時候月亮會變得非常神秘，這是因為發生了「月全食」。你知道嗎？其實即使是不同年份的月全食，看起來也會有很多相似的地方！最近的月全食發生在2026年3月，而上一次類似的月全食則是在2008年的2月。這兩次的月全食有一個共同點，就是它們來自同一個叫做Saros的週期！Saros週期就像是一個神秘的時鐘，告訴我們強大的太陽、地球和月亮何時會排成一條直線，讓月亮變成紅通通的樣子。這樣的週期大約每18年、11天又1/3天會循環一次，所以它們真的非常的相似哦！如果你這次錯過了月全食，別擔心！下一次在Saros 133系列中的月全食將會在2044年3月13日發生。讓我們一起期待吧！
原文:
Centered on maximum eclipse, these two total lunar eclipse sequences look almost identical. Yet the one shown on top is composed of images recorded in February 2008, while at the bottom is the recent March 2026 total eclipse of the Moon. Why are they so similar? Because these two total lunar eclipses are from the same Saros cycle. The Saros cycle was discovered historically from observations of the Moon’s orbit. With a period of 18 years, 11 and 1/3 days, the cycle predicts when the Sun, Earth, and Moon all return to the same relative geometry for a lunar (or solar) eclipse. Eclipses separated by one Saros period belong to the same numbered Saros series, in this case Saros 133. So expect the next lunar eclipse in Saros 133 to be a repeat of this year’s March 3 eclipse. You can watch the next Saros 133 total lunar eclipse on March 13, 2044. Growing Gallery: Total Lunar Eclipse of March 3
