Refraction
In glass and waterdrops. :)
All my photos, most unedited, though I did stage the ones on the ivy, using an eyedropper.

An astronaut took this photograph of the Aurora Australis in August 2017. At the time, the International Space Station was moving over the southern Indian Ocean towards the Great Australian Bight and Melbourne, Australia.

either the dragon theme from BotW was written Like That bc they knew what they would do with the dragons in TotK, or the composer read the script for TotK and let out the biggest evil cackle in the world. either way I am suffering

Does anyone out there also have a bit of a thing for “strange weather phenomenons” like these?!
Funny that they saw this outside of Munich while
Sleep Token
was there.
I'm not connecting this. No, no. No. Never. Would be weird. I'm really not connecting it.
I know what light columns are. I learned how to create them and put them somewhere. But I am not strong enough to make them visible. That was part of my energy work course that I did. Idk if you can believe me. You don't have to. Another good one is this:

A Brocken spectre also called Brocken bow, mountain spectre, or spectre of the Brocken is the magnified (and apparently enormous) shadow of an observer cast in mid air upon any type of cloud opposite a strong light source.

How Rainbows Form pt. 2
To add to a previous post, this one explains how rainbows appear to us as half-circles!
Ok, so other than the dispersion of light in raindrops, another factor in the occurrence of rainbows is seeing them. We do not see every individual rainbow formed from each droplet because we’re too far away to see them. Instead, we see different individual colors from different raindrops based on their height and angle from us. 
Tumblr media
A raindrop at a 42-degree angle from us relative to the sun would reflect red light to us and end up looking red. The other raindrops below it would look orange, yellow, green, blue, and indigo in the angles between 40 and 42 degrees. Violet would be below the other colors at a 40-degree angle from us and the sun.
This would also explain why we see rainbows as an arc or half-circle. According to Wikipedia, “A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the center”.
Tumblr media
The sun shines light on many points at once from its direction. For an observer to be able to see colors from a rainbow, the dispersed light reflected from the sun would have to reach them from an angle. This means that all the other raindrops reflecting colors to the observer would also have to reach their eyes at 40-42 degree angles, which also leads to all the points (in this case, raindrops showing color) being at similar distances away from the observer.
 To make this easier to understand, I tried to use a triangle ruler where the lines (base and hypotenuse) represented the path of the light from the sun to the observer’s eyes; the point of the triangle touching the ground would represent the observer.
Tumblr media
 If the triangle was tilted so that the point on the bottom stayed in its place, it would go in the direction of an arc. If all the points on this arc were mapped out, it would form a half-circle or at least part of one. 
Tumblr media
It would form a full circle if no ground or horizon were blocking the triangle ruler. This is the same for rainbows. Rainbows are full circles, but the lower half is usually blocked by the ground or horizon. This is also the reason why people on airplanes or in the sky can sometimes see rainbows as circles because the horizon does not block them.
Rainbows are also similar to mirages since they’re a result of the behavior of light, so unfortunately you can’t ride them or find any gold at the end. Additionally, the rainbow will move with you because only certain raindrops can form the rainbow you see depending on your position and location; Buttttt! this also means that everyone sees a different rainbow, which makes each rainbow as unique as the observers who look at one :) even though it may not look that way at first glance
I’m gonna stop writing about rainbows now but I hope this and the other post were good explanations for the formation of rainbows!

Light pillars
Light pillars is a natural optical phenomenon. It is an admirable and relatively common thing to see in the sky. These columns of light appear to beam upwards from unshielded lights and create an incredible view. Light pillars are most often seen during sunsets and sunrises. They can reach a height of 5° to 10° and sometimes even higher.
Tumblr media
This phenomenon is caused by the reflection of light from horizontal surfaces arranged horizontally by the free fall of flake ice crystals.
Tumblr media
The appearance of a column of light depends on its formation and the direction of incidence.
