Massachusetts Coastline in Sunglint: Bathed in sunlight reflecting on the water, the Massachusetts coast and

Each day, the Crew Earth Observations team at NASA’s Johnson Space Center sends specific ground targets for photography to astronauts on the International Space Station (ISS). But sometimes the striking displays visible from orbit provoke the crew to take imagery on their own. One such display—often visible to the ISS crew due to their ability to look outwards at angles between 0 and 90 degrees—is sunglint on the waters of Earth. Sunglint is caused by sunlight reflecting off of a water surface directly towards the observer—much as light reflects from a mirror. Variations in the roughness of the water surface scatter the light, blurring the reflection and producing the silvery sheen of a sunglint area. The point of maximum sunglint in this image is centered within Cape Cod Bay, the body of water partially enclosed by the “hook” of Cape Cod in Massachusetts (image right). (T...
