AURORA BOREALIS
Source/Credits : science.nasa.gov
Our Sun sends out particles regulary. Sometimes a burst of protons is sent towards Earth ; 2 or 3 days later the particles arrive near Earth where they are deflected towards the poles by the magnetosphere. The encounter of these particles and the atoms of our upper atmosphere (100 to 1000 km) give these magnificient light displays, we have an aurora !
