Aurora is the result of collisions between the Earth's gaseous particles and matter released by the Sun's atmosphere, according to the National Oceanic and Atmospheric Administration
It is known as aurora borealis, or the northern lights, in the northern hemisphere and aurora australis, or the southern lights, in the southern hemisphere.
The collisions can jar the magnetosphere around the Earth's north and south poles, releasing colourful streams into the sky.
The solar flares can have another unusual effect, at times disrupting global positioning, radio, and satellite signals.ards away, police have said as they deepened their investigation into the second racially charged armed assault on U.S. law enforcement this month.
