Aurora Borealis or Northern Lights
native american ppl called it “Dance of the spirits”

Aurorae are produced by the collision of charged particles fromearth 's magnetosphere](Magnetosphere - Wikipedia) mostly, but also and heavier particles, with and of Earth’s upper (at altitudes above 80 km (50 miles)). The particles have energies of 1 to 100. They originate from the Sun and arrive at the vicinity of Earth in the relatively low-energy When the trapped of the solar wind is favourably oriented (principally southwards) it connects with Earth’s magnetic field, and solar particles enter the magnetosphere and are swept to the magnetotail. Further magnetic reconnection accelerates the particles towards EarthThe collisions in the atmosphere electronically excite atoms and molecules in the upper atmosphere. The excitation energy can be lost by light emission or collisions. Most aurorae are and emissions from atomic Molecular and nitrogen produce some low level red and very high aurorae. The light blue and green colors are produced by ionic nitrogen and the neutral nitrogen gives off the red and purple color with the rippled edges. Different gases interacting with the upper atmosphere will produce different colors, caused by the different compounds of oxygen and nitrogen. The level of solar wind activity from the Sun can also influence the color of the aurorae
