科學圖說

2020年6月21日14:48,月球走入地球與太陽之間,三者成一直線,由本影延伸出的圓錐狀偽本影,剛巧落在地球上,投影在視網膜上形成小黑點,眾所矚目的日環食在臺灣雲嘉開始上演。隨著月球遮蔽太陽的食分越來越大,太陽越來越細,直至16:13,月球的剪影完全進入太陽裡,藕斷絲連的貝里珠漸進成為「上帝的指環」(食甚)。精彩的環食過程持續不到一分鐘,令人屏息,目不轉睛!貝里珠為太陽光被月球表面凹凸不平的地形阻擋所造成的,若將食甚前後的貝里珠的連續過程疊合排列,可模擬出月球表面之山峰。什麼!你錯過了這次日環食!?下次195年後請準時。圖1日環食連續過程;圖2食甚與貝里珠;圖3日環食月表山峰。

Introduction

At 14:48 on June 21, 2020, the moon came to a point between the earth and the sun and all three were lined up. The cone-shaped shadow projected onto the earth's surface looked like a small dark dot and an annual solar eclipse began in the area around Yunlin and Chiayi counties in Taiwan. As the magnitude of eclipse increased, the visible section of the sun narrowed. At 16:13, the moon covered the sun completely. Baily’s beads appeared and the “Ring of God” formed around the maximum of eclipse. The spectacular “Ring of God” lasted less than a minute. Baily’s beads were formed by sunshine piercing through the bumpy contour of the moon. If we align and overlap successive images of Baily’s beads, the contour of the moon will be revealed. If you missed it, the next one will be in another 195 years! Image1: A composite picture composed of successive images of the eclipse. Image2: Maximum of eclipse and Baily’s beads. Image3: The contour of mountains and valleys at the edge of the moon.
