So Many Ways to View an Eclipse
So Many Ways to View an Eclipse
On August 21, 2017, millions of Americans saw day turn temporarily to night as the Moon passed between the Sun and the Earth to create a total solar eclipse. As people in the 70-mile-wide (110-kilometer-wide) path of totality looked up and saw blinding light replaced by a dark circle and the Sun’s wispy corona, several Earth-observing satellites captured spectacular imagery of the Moon’s shadow as it raced eastward over the continental United States.
Here are a few of NASA Earth Observatory's favorite images of the eclipse. The first photograph is a composite, made from seven frames, that shows the International Space Station (ISS) as it transited the Sun at roughly 5 miles (8 kilometers) per second.
As seen in the second image, the astronauts had a unique perspective on the eclipse. This image shows the Moon’s dark shadow as seen from their vantage point on the International Space Station. The lunar shadow was visible near the Earth’s limb, the boundary between the atmosphere and space. The upper levels of the atmosphere faded from blue to black as clouds lower down bubbled up and around the shadow.
The third photograph was taken from NASA’s Gulfstream III jet while it was flying 25,000 feet (8,000 meters) above the Oregon coast. As the last bits of sunlight passed through valleys on the Moon’s limb, the faint corona around the Sun was just becoming visible, giving the Sun the appearance of a diamond ring. This effect, sometimes called Baily’s Beads, becomes visible just before and after totality.
The last image is a composite photograph that shows the progression of the total solar eclipse over Madras, Oregon.
