“Last Sunday, Oct. 13, American astronaut Karen Nyberg tweeted this excellent photograph of the Great Lakes taken on Aug. 23 from her vantage point orbiting the Earth aboard the International Space Station.She posted the image on Twitter about 4:40 p.m., generating a cascade of re-tweets. As spectacular photos are wont to do, the image has spent the meantime making rounds on Facebook and other social media platforms.The image shows four of the five Great Lakes. The sun’s glint brightens lakes Erie and Ontario to the east, while lakes Michigan and Huron are seen in shades of deeper blue. Lake Superior and most of Michigan’s Upper Peninsula are not in the frame.”
