Watching the aurora borealis. Silhouetted human figure on the skyline, watching the aurora borealis, a coloured light display (the northern lights) that is visible in the night sky at high latitudes. It occurs when charged and energetic particles from the Sun (the solar wind) are drawn by Earth's magnetic field to the polar regions. Hundreds of kilometres up, they collide with gas molecules and atoms, causing them to emit light. A meteor trail is seen at upper right. Photographed in Hemnesberget, Nordland, Norway. | |
