No, not Southern Lights. Southern Lights (otherwise known as aurora australis) are similar to the Aurora Borealis just in the Southern Hemisphere. This effect is called crepuscular rays which are actually parallel beams of light, and not diverging as they appear. This is an illusion caused by perspective. The sun is so far away that the light reaching the earth is fairly well collimated and obstructions such as clouds or mountains cause bright beams of light, or darks shadows, in the atmosphere which are very close to parallel and just appear to converge or diverge. The further away something is, the smaller it looks. This is what causes the edges of a straight road or railway tracks to look like they converge in the distance. This is called perspective.Originally Posted by JDd
