Sometimes, a total eclipse is a good time to eye the Sun. Taking advantage of an unusual juxtaposition of Earth, Moon and Sun, the featured image depicts the total solar eclipse that occurred last month as it appeared — nearly simultaneously — from both Earth and space. The innermost image shows the total eclipse from the ground, with the central pupil created by the bright Sun covered by a comparatively dark Moon. Surrounding the blocked solar disk is the tenuous corona of Sun imaged in white light, easily visible from the ground only during an eclipse. Normally, this corona is hard to track far from the Sun, but the featured montage matches it to false-colored observations of the Sun from NASA and ESA’s space-based, Sun-orbiting, Solar and Heliospheric Observatory (SOHO). Observations like this allow the study of the constantly changing magnetic activity both near and far from the Sun, the same activity that ultimately drives Earth’s auroras. APOD is also available in: Arabic, Bahasa Indonesian, Catalan, Chinese, Chinese, Croatian, Czech, Dutch, Farsi, Farsi, Galego, German, French, Hebrew, Japanese, Korean, Montenegrin, Polish, Romanian, Russian, Serbian, Slovenian, Spanish, and Turkish

🌒 有時候，總日蝕正是觀察太陽的最佳時機。借助地球、月亮和太陽之間的不尋常相對位置，這張精選圖像展示了上個月發生的總日蝕，幾乎同時在地球和太空中觀測到的情況。內部圖像展示了從地面看到的總日蝕，明亮的太陽中央圓形被相對較暗的月亮所覆蓋。環繞著被遮擋的太陽光碟的是太陽的微弱日冕，這在日蝕期間才能從地面輕易觀察到。通常，這種日冕在太陽遠處難以追踪，但這個特別的拼貼圖將其與來自美國宇航局（NASA）和歐洲航天局（ESA）太陽軌道觀測站（SOHO）的虛假彩色觀測相匹配。這些觀測使我們能夠研究太陽附近和遠處不斷變化的磁場活動，這種活動最終驅動著地球的極光。
