日食日冕詳圖
Detailed View of a Solar Eclipse Corona

只有在日全食稍縱即逝的黑暗中，日冕的光芒才會清晰可見。日冕是太陽的外層大氣，通常被明亮的太陽圓盤所淹沒，廣闊的日冕是一道誘人的風景線。但是，日冕的微妙細節和極端亮度範圍雖然肉眼可辨，卻很難拍攝。本圖是 2023 年 4 月 20 日日全食期間從澳大利亞埃克斯茅斯拍攝的日冕細節影像，採用了多幅影像和數字處理技術。清晰可見的是熱氣和磁場不斷變化的混合物所形成的錯綜複雜的層次和熾熱的苛色。明亮的環狀突出物在太陽邊緣呈現粉紅色。在距今六天後的日全食期間，透過晴朗的天空，在北美的狹長地帶可能會看到類似的日冕 美國宇航局報道： 2024 年日全食 4 月 8 日
原文：Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun's outer atmosphere, is an alluring sight. But the subtle details and extreme ranges in the corona's brightness, although discernible to the eye, are notoriously difficult to photograph. Pictured here, however, using multiple images and digital processing, is a detailed image of the Sun's corona taken during the April 20, 2023 total solar eclipse from Exmouth, Australia. Clearly visible are intricate layers and glowing caustics of an ever changing mixture of hot gas and magnetic fields. Bright looping prominences appear pink just around the Sun's limb. A similar solar corona might be visible through clear skies in a narrow swath across the North America during the total solar eclipse that occurs just six days from today NASA Coverage: Total Solar Eclipse of 2024 April 8
