<human>:  What is the difference between the Northern and Southern Lights?
<bot>: The Northern Lights, or aurora borealis, are natural light displays caused by the collision of charged particles from the sun with atoms in the Earth's atmosphere. They usually occur in an oval around the North Pole and usually appear as bright green or pink lights in the sky. The Southern Lights, or aurora australis, are similar to the northern lights but are located in the southern hemisphere, usually appearing near the South Pole as bright red, yellow and green lights in the sky.
