“Aurora Over Iceland” is copyrighted by Daniel Lopez (El Cielo de Canarias). NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteAn aurora glows over the Vatnajökull glacier in Iceland. This 180-degree panorama captures the full extent of the light show. Auroras are caused by energetic particles from the Sun colliding with Earth's magnetic field. These collisions excite atoms in the atmosphere, causing them to emit light.
