原文:
During a total solar eclipse, the Sun’s extensive outer atmosphere, or corona, is an inspirational sight. Streamers and shimmering features that engage the eye span a brightness range of over 10,000 to 1, making them notoriously difficult to capture in a single photograph. But this composite of 29 telescopic images covers a wide range of exposure times to reveal the crown of the Sun in all its glory. The aligned and stacked digital frames were recorded in the cold, clear skies above the Arctic archipelago of Svalbard, Norway during the Sun’s total eclipse on March 20 and also show solar prominences extending just beyond the edge of the solar disk. Remarkably, even small details on the dark night side of the New Moon can be made out, illuminated by sunlight reflected from a Full Earth. Of course, fortunes will be reversed on April 4 as a Full Moon plunges into the shadow of a New Earth, during a total lunar eclipse.

在一次全日食期間，太陽的廣闊外層大氣，即日冕（corona），是一幅鼓舞人心的景象。流線和閃爍的特徵延展了超過 10,000 比 1 的亮度範圍，使它們在單張照片中捕捉到這些特徵變得十分困難。但這幅由 29 張望遠鏡圖片組成的合成圖像則涵蓋了廣泛的曝光時間，展示了太陽的王冠，盡展其壯麗。在寒冷、清澈的北極群島斯瓦爾巴（Svalbard）上空拍攝的數字影像，記錄了 3 月 20 日日全食期間的美景，還顯示了延伸至太陽圓盤邊緣的太陽色球（solar prominences）。值得注意的是，即使在新月的黑暗夜側，小細節也能夠被看見，這些細節是由反射從滿月的地球所照亮的。當然，隨著滿月於 4 月 4 日進入新月的陰影，在一次全月食中，這些景象將會顛倒過來。
