What’s even sader: The universe is expanding with the speed of light. Some time in our future the light of distant suns won’t reach us, ever. So people will look into the sky not seeing stars. When civilization gets wiped out and another cycling of intelligent live begins they will never be able to observe far away stars, can’t come to the Big Bang conclusion- they will be alone, with our galaxy being the only observable thing in the sky. :/

Why couldn't they come to the big bang conclusion? We haven't seen the exact beginning of the big bang, either.

But we see stars expanding, radiation that supports the theorie etc the sky is full of information and stars.

Sometimes down the line you won’t see other stars except the sun in the sky, therefore never know that there are more stars in the universe you’ll not have any reason to suspect anything is expanding and therefore not come to the same conclusions we could think about.

No light or other measurable radiation will reach earth. A Webb style telescope in space will only output black pictures if pointed at open space.

Apples aren't red for any particular reason. This can get a bit philosophical but how can you be sure that the red apple you see is the same red I see? Maybe your red is my blue and we just use the same words to describe it.
What about tetrachromats? People that have 4 color channels instead of 3. Is their view of reality less accurate because it isn't the norm?

Nature exploits color just like we do. Fruits, flowers, etc use color because there is an advantage to it. Even if insects or whatever can't perceive the various wavelengths we do doesn't mean the "color" of one thing isn't distinguishable from the color of another and serve to attract or repel. So there is an objective use for color beyond what hmans make up in their head.

As for "is my red the same as your blue" I's argue the ability for humans to color match and for large groups to successfully interpret color dot diagrams like this

suggests that most humans perceive color in the same way. I've heard that women have a greater ability to distinguish between shades though, which may explain why my wife can hold up two bright red shoes and ask me which one goes better with her dress, I say "they are the EXACT SAME COLOR", and then I sleep on the couch that night

Anyway, I'm ok with heightening the color of observed celestial bodies. If you were in a spaceship just outside some gas nebula 10 AUs across I doubt you could see it with the naked eye, it'd be too dim.

Check out backyard telescope pictures of galaxies. Less post processing typically and still an amazing sight to see.

Very true, if you live in an area with a clear night sky. I have a buddy in Las Vegas and the stuff he can capture with a (relatively) simple set-up by his pool is amazing.

Space images are nothing to brag about, making contact with another galaxy will be important, giant commercial buildings on Mars, maybe alien influence. Space images were important in the 70s and 80s in my mind it’s 2022 id rather see mars, meaningful things that have Star Wars and mass effect type feelings.

That is an amazing photo. The wonders of technology and our natural universe never cease to amaze me.

That looks like a zoomed in shot of Uranus

Actually the universe is expanding in many parts faster then the speed of light. They say no matter how advanced we get, even millions of years in the future, we'll never see these places.

100 million years earlier than Hubble.
I wonder if it's possible when enough of these are found to deduce the size and motion of the rest of the universe from data.

I find it a bit questionable that they can put dates and distances on things at this scale. How do they know its 33 Buh Buh BILLION LY away? That just seems like a speculative estimate based on other observations we also have no real way of confirming. I'm assuming it's based on some sort of extreme red shift pattern but still.

My guess is the Trappist-1 system will be a bunch of venuses at the front and airless ice balls at the back.

There’s observation methods for all types of ranges, with redshift being the one for the farthest. Based on Hubble’s expansion theory, galaxies have a velocity. That velocity has an observable shift with the Doppler effect.

https://starchild.gsfc.nasa.gov/docs/StarChild/questions/question39.html

I trust they measure at the best of their current accuracy. It’s unknown how much JWST is reducing the margin of error by being the most photon sensitive tool and red shift specialist tool humans have ever created, but if the supernovae candle technique is with 5% error up to 13.2B years, I’m taking a guess that JWST is better than that.

I'm sure that is all great math, but the reality is that we have an extremely small observational window, just a few decades at best, to describe movement of BILLIONS OF LIGHT YEARS and really no way to confirm any of it. Not saying it's all a smoke show, just that I suspect that astronomers in 200 years will look back at our statements now and laugh, much like we would to a 15th century astronomer.

Your question did seem to be about epistemology.

You gotta love people who just call all this BS, they can't measure stuff like that, NOOOOOOOOOOOOO!! When in reality they have ant brains that can't comprehend the numbers/math involved. Just say this is way over your head and be done with it instead of shitting on the work of tens of thousands of people.

Exoplanet Apparently Disappears in Latest Hubble Observations - NASA Science

Now you see it, now you don’t. What astronomers thought was a planet beyond our solar system has now seemingly vanished from sight. Though this happens in science fiction, such as Superman’s home planet Krypton exploding, astronomers are looking for a plausible explanation. One interpretation is...

www.nasa.gov

One interpretation is that, rather than being a full-sized planetary object, which was first photographed in 2004, it could instead be a vast, expanding cloud of dust produced in a collision between two large bodies orbiting the bright nearby star Fomalhaut. Potential follow-up observations might confirm this extraordinary conclusion.
"These collisions are exceedingly rare and so this is a big deal that we actually get to see one," said András Gáspár of the University of Arizona, Tucson. "We believe that we were at the right place at the right time to have witnessed such an unlikely event with NASA's Hubble Space Telescope."
"The Fomalhaut system is the ultimate test lab for all of our ideas about how exoplanets and star systems evolve," added George Rieke of the University of Arizona's Steward Observatory. "We do have evidence of such collisions in other systems, but none of this magnitude has been observed in our solar system. This is a blueprint of how planets destroy each other."

Gáspár and Rieke — along with other members of an extended team — will also be observing the Fomalhaut system with NASA's upcoming James Webb Space Telescope in its first year of science operations. The team will be directly imaging the inner warm regions of the system, spatially resolving for the first time the elusive asteroid-belt component of an extrasolar planetary system. The team will also search for bona fide planets orbiting Fomalhaut that might be gravitationally sculpting the outer disk. They will also analyze the chemical composition of the disk.

So haute right now.

All I see is a planet from a long time ago, in a galaxy far far away, suddenly exploding….

 

[Biff]

The idea that all this shit we are seeing is within the size of a grain of sand held at arm's length pointed up to the sky has cemented my belief that the reason we haven't detected extraterrestrial intelligent is not because we are too dumb or they are observing us like zoo animals or whatever... It's very simply that the universe is so unfathomably vast that the odds of us looking in the right grain of sand within the past 20 (30?) years of space observation technology is too infinitesimally small.

We need hundreds of Webbs taking images over years and years before we can finally get lucky enough to see something identifiable within the universe.

And even then, we will need to be lucky enough that the aliens we see still operate in our caveman third dimensional understanding, and they aren't on some fourth-dimensional plane we simply don't understand yet.

Have you guys seen? JWSTs first exoplanet photo has been released. I'm on mobile now with no time to get a link. Pretty exciting stuff.
