Natural phenomena: Sun dogs

Here’s another phenomenon that has to do with ice crystals in the atmosphere. Like fire rainbows, sun dogs are massive halos in the sky as a result of light refraction—though in this case, they appear to actually encircle the sun. Sun dogs can be recognized by the two distinctive bright spots on either side of the halo—if these blips are bright enough, it can even look like there are three suns in the sky, all side by side. And the good news is that this happens all the time, all over the world, so you’ll be able to start seeing them if you look closely enough (especially when the sun is low in the sky). Just remember that if you look closely enough at the sun for too long, you won’t be able to see much of anything. Ever. So try to be careful.
