This is the Great American Solar Eclipse as seen from the stratosphere.
On August 21, 2017, the students of Earth to Sky Calculus launched 11 space weather balloons from the path of totality as the Moon covered the sun overhead. This high-resolution photo shows the Moon’s inky-black shadow blotting out a 70-mile wide patch of Nebraska. It was taken by a Panasonic GH4 digital camera floating 105,000 feet above the launch site in Fort Laramie Wyoming.
The 11″ x 17″ poster, printed on premium glossy paper, is ready for framing. BONUS: The poster comes with a 5″x 7″ postcard showing the same scene and telling the story of the photograph on the back of the card.
