An aurora [a] (pl. aurorae or auroras), [b] also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), [c] is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains ...
The northern lights, or aurora borealis, is a natural phenomenon that has enchanted humans for thousands of years. The light display in the sky is caused by cosmic rays, solar wind and ...

X-Ray image of aurora borealis taken during an ionospheric storm by the Global Geospace Science Polar satellite. Ionospheric storms are storms which contain varying densities [1] of energised electrons in the ionosphere as produced from the Sun. Ionospheric storms are caused by geomagnetic storms. [2]
The profile of the ionosphere is highly variable, changing constantly on timescales of minutes, hours, days, seasons, and years. This profile becomes even more complex near Earth's magnetic poles, where the nearly vertical alignment and intensity of Earth's magnetic field can cause physical effects like the aurora.

Birkeland's theory of the aurora continued to be dismissed by mainstream astrophysicists after his death in 1917. It was notably championed by the Swedish plasma scientist Hannes Alfvén, [9] but Alfvén's work in turn was also disputed by Chapman. [10] Proof of Birkeland's theory of the aurora only came in 1967 after a probe was sent into space.
