Looking out at the Earth’s surface from the International Space Station (ISS), astronauts frequently observe sunglint highlighting both ocean and inland water surfaces.
The coast of the northeast United States is silhouetted against the shimmering water of Cape Cod Bay and Long Island Sound in a new photo captured by astronauts on the International Space Station.
The phenomenon of light from a setting sun reflecting off water to create a shining, mirrorlike surface is called sunglint, and is evident throughout the photo.
"The Atlantic Ocean — including Cape Cod Bay and Buzzards Bay, along the coastlines of Massachusetts and Rhode Island — has a burnished, mirrorlike appearance in this image," the NASA's Earth Observatory wrote. "This is due to sunlight reflected off the water surface back towards the astronaut-photographer."
