Today’s Image of the Day comes thanks to the NASA Earth Observatory and features a variety of ice formations in the Caspian Sea. The photo was taken by the Operational Land Imager (OLI) on the Landsat 8 satellite.
The Caspian Sea measures 600 miles in length, stretching from Kazakhstan to Iran, making it the largest enclosed inland body of water on Earth. The northern portion of the sea experiences cooler temperatures and less saline water, making it much more susceptible to freezing during the winter. This northern portion, also known as the Caspian Depression, is one of the lowest points on Earth.
