An aurora, sometimes referred to as a polar light, is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic)…
Like a wisp of electric green smoke, the aurora australis seemingly intersects with the Earth's airglow as the International Space Station orbited above the Indian Ocean halfway between Australia and Antarctica. Ever-shifting displays of colored ribbons, curtains, rays, and spots, auroras are most visible near the North (aurora borealis) and South (aurora australis) Poles as charged particles (ions) streaming from the Sun (the solar wind) interact with Earth’s magnetic field.
Beautiful display of Aurora Borealis or the Northern Lights lit up the sky over a Sami village in Lapland, northern Sweden. When aurora is very active it often displays its most beautiful form known as aurora corona. It appears near the zenith. Its form can appear to boil with motion, its colors can range across the entire spectrum and, when bright, it can easily cast a shadow. Aurora is produced by the collision of charged particles from the magnetosphere with atoms/molecules of the atmosphere.
