My friend Millisa sent me this pic the other day, and it kinda blew my mind:
Those rays! Â Holy crap! Â SO BEAUTIFUL! Â That’s the stuff that paintings are made of, right? Â Funny enough, they actually have a real name and an explanation – they’re called crepuscular rays. Â It’s kind of an unfortunate sounding name, don’t you think? Â It sounds like something you’d find on the bottom of a ship cruising Lake Michigan.
But the principle is very awesome – atmospheric optics dictates these crepuscular rays as beams of light that appear to emanate from one single point in the sky, from the sun. Â A cloud, mountain top, or some other obstruction is what causes this phenomenon. Â Honestly, it’s no different than the beam that comes out of a moving light, conventional light, or anything of the sort. Â It’s a blockage – just like the aperture of a lighting fixture is a blockage to only allow enough beamage out of the light to make it diverge, or appear to diverge. Â Like this:
There are also anticrepuscular rays, too – they are the opposite of crepuscular rays, and typically you have to have your back to the sun to see them. Â Anticrepuscular rays appear to converge at the antisolar point, which is the exact opposite point in the sky from the sun. Â Like this:
Cool. Â I like to learn something new every day!
