Combined Solar Eclipse Corona from Earth and Space
			
		
		
		
			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.
