Corona from Svalbard
Explanation: 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.
