This is a photo of a “fire rainbow”. Technically,it is known as a circumhorizontal arc which is an optical phenomenon caused by clouds which contain water and ice droplets of nearly uniform size. These clouds diffract sun light which separates the light into different wavelengths, which we perceive as different colours.Although they look similar to rainbows in their colour arrangement; the mechanism by way the light is scattered to produce them is different.Rainbows are the result of refraction and reflection. When light is refracted, it is bent by passing through mediums of different densities, such as water. Reflected light bounces off a surface at an angle equal to the angle it hit the surface at. Diffraction, however, involves light waves being scattered into a pattern; creating what you see here.The clouds needed for these rare events have to be cirrus and at least 20,000 feet in the air, with just the right amount of ice crystals. The sun also has to hit the clouds at precisely 58 degrees.-JeanPhoto courtesy of Raymond Lam

the year is 2046. no one has memed in 15 years since king obama the third make memeing illegal. in the dystopian suburbs of fort lauderdale, sixteen year-old Dogecoin de Grasse Sagan found a sexy fedora in an trash dumpster. he put it on and it made a sweet anime noise. he knew then he, was destined to bring memes back to this stupid idiot planet. he looked at the camera and goes “u mad, world?”
