Dusk over the Americas, Earth globe. Computer graphic of a crescent Earth globe centred on the northern Atlantic, generated using satellite and mapping data. The data combines cloud-free satellite images of the land and sea surface in natural colour, plus ray-traced atmospheric haze. The globe is shown with the correct axial tilt, with sunlight from the left, highlighting the Americas, with the Atlantic Ocean, much of the Arctic, eastern Brazil, and all of Europe and Africa in shadow. The lit areas of the globe will move into darkness from the sunlight as the Earth's rotation moves them across the dusk terminator (day-night line).
