| Description: A deluge of charged particles from the Sun can overload the Van Allen belts and cascade toward Earth, producing auroras that can be seen over a wide range of latitudes. This is a view of an aurora from the deep space satellite Dynamics Explorer 1. The green lines show the locations of land masses under the aurora. Auroras typically occur 100 to 400 km above Earth’s surface Picture Stats: Views: 628 Filesize: 511.05kB Height: 900 Width: 904 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=15972 |
