Sun pillars or light pillars form when sunlight (or another bright light source) reflects off the surfaces of millions of falling ice crystals associated with thin, high-level clouds, for example, cirrostratus clouds. The ice crystals have roughly horizontal faces. They are falling through Earth’s atmosphere, rocking slightly from side to side.
They will reflect natural and artificial light that extend in columns that extend through the sky. The one below was created by lightning (rare sight)...

Is it Van Gogh or Jupiter?
Jupiter, actually. (As if you really didn't know this). This shot was taken during a Perijove pass as Juno flew by the gas planet.

A super sharp capture of the Pillars of Creation in Eagle Nebula in Serpens constellation by the James Webb telescope.
Also, here is a little perspective - the true size of our moon compared to Earth.

Not totally related but has anyone watched Life On Our Planet on Netflix? Morgan Freeman narrates it, and produced by Steven Spielberg. It’s pretty interesting, and done very well. I just wish it would have been about 8 episodes longer, and go into more depth in certain areas/aspects..

Not to go all Cliff Clavin on y'all, but the "dark side" with respect to that photo posted above (which is very cool) is the other side. The "dark side" sobriquet refers to the side that always faces away from the earth -- yet another of the moon's silly party tricks.
Even Wiki-p refers to it as the "far side" of the moon -- although I am not sure how Gary Larson might feel about that.

I'm pretty sure (seeing as, how there is zero light reflecting off of that image) that this is, in fact....the dark side of the moon.

Back in 1988 or so, my boss and I had an actual bet, we shook on it and I knew I would win. It was on this exact topic.
2K was the bet. 2k!!!
"Dark side of the moon"....
We called, I don't know how many national planetariums and got the run around. He would present his side and they agreed and he let me listen. Then I asked them questions and all of a sudden? They agreed with me.
Probably 2 years went by without that question actually being answered by the, "professionals".
We both gave up after that.
The bet was never settled. FWIW.
We did, however have a whole bunch of fun asking people from all walks of life this question. Some were stupid answers, some were beyond belief, some were logical but flawed and some were flat out hilarious.
"What is the dark side of the moon and what causes it"?
That was the question.....

The moon doesn't rotate, it is locked. We only ever see one side of the moon which is reflecting light from the sun and earth. The dark side is facing away- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

The far side or the dark side?
During an eclipse? The dark side is facing toward us...

I'm not sure I follow, we always see the same side of the moon... It never changes
During the total solar eclipse that’s set to occur, the far side of the Moon will be completely bathed in sunlight as the Moon blocks the Sun from Earth’s view. However, even the 2024 solar eclipse won’t alter the fact that we always see the same side of the Moon. This phenomenon is due to Earth’s gravity and the Moon’s rotation1
The dark side is simply the side not receiving reflected light from the sun.
So in an eclipse the side we see would momentarily be the dark side but it's ultimately not a different side of the moon.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
Pink Floyd "DARK" side of the moon
"DARK" implies "Unknown", "Unseen", "Hidden", "Mysterious ", "Trippy"
It makes one quizzical, searching for what's "out there". 🤔
"Far Side" might be something one's grandma might come up with in her Canasta Club
Grandma's a nice lady, but... Sorry Grandma, we're sticking with the correct

The moon does indeed rotate. It doesn’t appear to from our perspective because its period of rotation is the same duration as its period of revolution.
-
It doesn't rotate.
It revolves.
If you attach a tennis ball to the end of a string and swing it around your head, it doesn't rotatate, it revolves.
The only way I can make this explanation any easier is if I personally demonstrate by showing up at your housr.
I will, of course, expect a complimentary meal and beverage for my services.

It rotates AND revolves. Rotation is a spin on its axis. Revolution is an orbit (in this case, around the Earth). The fact that it rotates once every 28ish days and makes a revolution in the same 28ish days allows us on Earth to see only one side of the Moon. If it didn’t rotate, as you said, we’d see all of the Moon during the month
Take your tennis balls and put them on them the ground. If you leave one alone and make the other revolve around it, you will need to spin that other ball once per revolution in order to keep the same side facing the stationary ball. Alternatively, keep spinning the tennis ball around your head and have someone else look down on you as you do this. That person will see that the tennis ball rotates exactly once for every time it revolves around your head.
It’s about perspective. Looking at the Moon from space, it rotates. I’d like a rare ribeye and a glass of Aardbeg, please. -

At the end of the day and after 2 years of my boss and I talking much smack to one another, we both mutually ended up cancelling the bet. The question was,
"What is the dark side of the moon and what causes it?"
We were both correct. It was just that the question was flawed from the get go. He was correct in his stance that it was the side of the moon we never see (which to me was the far side, not the dark side) but that wasn't my question. The bet was what caused the dark side of the moon. In my mind, I was referring to the unlit portion of the moon. In his mind, he was referring to the dark/far side of the moon.
We did find it funny that of all of the planetariums we called to get an "official" answer? They would all end up agreeing with the both of us. We both told them what was riding on the bet, and that we were in search of the official answer.
The truth is, that the question itself was flawed. We did have a lot of fun talking smack and asking people this question. Some of the answers left you scratching your head, seriously questioning the intelligence of some folks and other answers were flat out hilarious.
Of course, this was back in 1988-1990 before the days of Google and folks were more interested in a dress and some chick, name of Monica Lewinski.

A solar prominence captured by a small telescope in Gilbert, Arizona. The monsteresque plume of gas was held aloft by the ever-present but ever-changing magnetic field near the surface of the Sun. Our active Sun continues to show an unusually high number of prominences, filaments, sunspots, and large active regions as solar maximum approaches in 2025.
