Just heard this about the space telescope Chandra
(X-rays).
ÑOT a political post but it does involve Congress.

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". 🤔

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.

It’s not like we fully understand the physics of our sun… we think it might tick on for another 5 billion years, but then again, it could go nova tomorrow and that ruin your plans for the weekend real quick.The Gear...

Going nova is not something that could happen tomorrow. That happens with white dwarfs that accumulate hydrogen gas at the surface (typically pulling it from a nearby red giant) until the surface layer of hydrogen reaches critical pressure and starts fusion, at which time, it blows itself out in a "nova." Not a supernova, that's a different process. Either way, these things take a long time to happen.For rig details, see my profile. Nothing here anymore... -
The James Webb Space Telescope (JWST) just released a new image of a pair of colliding galaxies; NGC 2207 and IC 2163.
NGC 2207 and IC 2163 are a pair of colliding galaxies situated 114 million light years away in the constellation Canis Major. NGC 2207 has a diameter of 143,000 light years, and IC 2163 has a diameter of 101,000 light years.
Due to the interaction, NGC 2207 has distorted the shape of IC 2163, flinging out stars and gas into long streamers stretching out a hundred thousand light-years toward the right-hand edge of the image.
The calculations indicate that IC 2163 is swinging past NGC 2207 in a counterclockwise direction, having made its closest approach 40 million years ago. However, IC 2163 does not have sufficient energy to escape from the gravitational pull of NGC 2207, and is destined to be pulled back and swing past the larger galaxy again merging into a single, more massive galaxy in billions of years.

Galaxies gobbling up other galaxies is actually quite common. Andromeda has reportedly gobbled up more than 30 other galaxies since its inception.
FYI - The Milky Way and Andromeda are also ultimately destined to collide with each other, according to astronomers. The merger is said to have already begun (star swapping). That said, there is nothing to be worried about for another 4 to 8 billion years from now.....a blink of an eye in space terms.
One thing that may thwart this merger is (in 2 billion years) the Large Magellanic Cloud. This may throw the Milky Way out into interstellar space. For a VERY technical report on this, I'll link the Royal Astronomical Society's article from 2019 about this cloud. For of a layman's term of this cloud, just run a search.
https://academic.oup.com/mnras/article/483/2/2185/5181341
Here is a quote from the Introduction section from that link.The Universe is a dynamical system: galaxies are continuously growing and undergoing morphological transformation. For the most part, this is a slow, unremarkable process, but from time to time evolution accelerates through spectacular galaxy mergers. The Milky Way (MW) appears to have been quiescent for many billions of years but its demise has been forecast to occur when, in several billion years time, it collides and fuses with our nearest giant neighbour, the Andromeda galaxy (van der Marel et al. 2012b). This generally accepted picture ignores the enemy within – the Large Magellanic Cloud (LMC).
