Explanation: Making landfall in Oregon, the Moon's dark umbral shadow [7]
toured the United States on August 21. Those gathered along its coast to coast
path were witness to a total eclipse [8]  of the Sun, possibly the most widely
shared celestial event [9]  in history. But first, the Moon's shadow touched
the northern Pacific and raced eastward toward land. This dramatic snapshot
was taken while crossing the shadow path [10]  250 miles off the Oregon coast,
45,000 feet above the cloudy northern Pacific. Though from a shorter totality,
it captures the eclipse before it could be seen from the US mainland. With the
eclipsed Sun not far above, beautiful colors appear along the western horizon
giving way to a clear, pitch-black, stratospheric sky in the shadow of the
Moon.
