Whirling and Swirling

In the Gulf of St. Lawrence, currents swirl. From NASA, "Orbiting above eastern North America, a crew member on the International Space Station photographed a dense pattern of eddies in the Gulf of St. Lawrence. Caught briefly in the Sun's "glint point," reflections off the water surface show an interlinked mass of swirls and eddies in the shallow water north of Prince Edward Island."

Deep, Dark Blue

From space, the Sacred Swan Lake in Tibet. From NASA, "Yamzho Yumco (Sacred Swan) Lake in Tibet is surrounded by snow-capped mountains and is one of the three largest sacred lakes."

Winter Solstice

After winter solstice, this image of northern Canada from space was taken. From NASA, "Just hours after the winter solstice, a mass of energetic particles from the Sun smashed into the magnetic field around Earth. The strong solar wind stream stirred up a display of northern lights over northern Canada."
