Hey, I'd never thought about it...but you're absolutely right. That's an unimaginable distance to us in thinking about it or even considering how much is floating between here and there. This is what is in close, for that matter.
I've wondered for awhile now if someday we're going to find out that looking out from Earth will end up being like a side view mirror in a car. "Objects may be closer than they appear". That would be both exciting and real sobering, wouldn't it?
Source: Astronomyca.ca - "Zone of Avoidance":
zone of avoidance Region of the sky near the plane of the Milky Way, where dust absorption and the high concentration of stars make it difficult to locate other galaxies optically. It typically spans 10° on either side of the galactic plane. Some kinds of galaxies in the zone of avoidance can now be detected by their radio, infrared or X-ray emissions, which are less vulnerable to dust and gas absorption. Surveys of such galaxies are important for tracing large-scale structure, since some important nearby superclusters and the great attractor either cross the zone of avoidance or lie mostly within it.

NEW STAR IN THE SKY: Around the world, amateur astronomers are turning their telescopes toward minor constellation Delphinus where a new star has appeared. Koichi Itagaki of Yamagata, Japan, discovered the nova on August 14th. At the time, the stellar brightness was +6.3. Since then it has continued to brighten, crossing the 6th magnitude threshold of naked-eye visibility. John Chumack photographed the surging nova on August 15th from the John Bryan State Park in Yellow Springs, Ohio:

So what i don't understand is if we are moving through the galaxy at thousands of miles per hour and moving up and down in the plane how do we always see the same stars? Are other galaxy's moving at the same rate that we are? How do they make their sky charts when we are all moving and sky apps show accurately, this all confuses me In the risk of sounding stupid can someone explain??
How do we pass through the same meteor showers year after year and how does a comet swing so far out and still find it's way back to it's orbit do we all travel on the same plane and orbit,, can nothing take that comet out of it's path and how does JPL keep that orbit true?

So if they just discovered a new star, is that in a different galaxy and is that galaxy colliding with our own and how many new stars are we going to see when more collide, if that is what is happening...

Trying to find a relevant thread to post this in, and this thread kinda fits the bill - apologies if it is a little off tangent to what the OP is asking:
In thinking why Luna shots of the Moons sky are so dark with no stars I searched and came across a rare video of the late and great Neil Armstrong talking to the also late an great Sir Patrick Moore, where he clearly states, very clearly, that you cannot see stars from on the Moon or in 'cisluna space', i.e. the area of space between the Moon and the Earth.
This contradicts what people in the thread state, and even what NASA say! that the Earth's atmosphere is blurring the visibility of stars..so in space and on the Moon they would be super Bright and clear...but Neil Armstrong who has been there says otherwise.

Anyway my question is - can we (with our eyes not a camera) see distant stars in space or can't we?
..and the very bright sunlight on the surface of the Moon.

I.e. Hipparcos 5926 in Cassiopeia is 16,308 light-years away. One light year is 9.4607 × 10*12 km. How come we can see that star without any major flickering? Seeing a star means that the light traveled an almost unimaginable distance without being absorbed, or blocked along the way. I feel the photons should have hit something along the way, i.e. planets, gasses, suns, space debris, etc.. The universe is full of moving objects. Yet, we see that star continuously shinning at night?

NASA went to a lot of trouble to identify the problems of low light condition, but I can find no papers on the problems of blinding sunlight, which they should have been more worried about if the Sun was brighter than anything we have ever experienced on Earth.
Another thing I have never seen used on the Moon was a colour calibration chart, or white balance card. Surely they would need that to be able to get true colours for processing or post-processing purposes?

David Scott: (in july 1971 commander of Apollo 15) "Can you imagine finding a green rock on the Moon? Think about that. We'd never had any green rocks in training. Nobody'd ever said anything about green rocks - orange, or anything - and all of a sudden you're sitting there and, you find a green rock! I missed it; Jim (LMP James Irwin) saw it. I didn't see it; and then I saw it; and it was really green.

I'm not going to get into the first part of your post, considering I'm exhausted from trying to convince gary-whats-his-name that a photon does not need atmosphere to be seen (considering the Apollo astronauts used an optical sextant to navigate by star).
The second part of your post though...
Why would you say they are long gone?
We know stars live for billions of years (such as our sun, which has been around for almost 5 billion years), and the stars we see in the sky are only a few hundred to several thousand light years away. Why would they be gone, if we are seeing them as they were only a couple of thousand years ago?
Yes, I think I'll have to defer to your obviously superior study of the Lunar surface and lighting, if they saw coloured rocks the Sunlight must have a good wide spectrum, and be of sufficient intensity. Well done wildespace!

The gold film on the visor is a crock, just like the gold foil on the lander. Kubrick said they need to spice things up a bit, it was too dreary up there.
