Term: | Aurora |
Definition: |
An aurora is a natural display of light in the night sky that typically occurs in far northern and southern regions. Auroras occur when incoming charged particles from the sun strike oxygen and nitrogen some 60 to 200 miles up in Earth's atmosphere and release a flash of light and heat. Electrons and protons released by solar storms add to the number of solar particles, and can createght auroras at lower latitudes. |
