"Explanation: 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. "

Enjoy!
