Funny enough, if you showed someone these two images without additional context, I'd wager the majority would think that the left one was taken by a modern telescope in 2022 and the right one from an older one decades ago.

The right one makes me think of a cheesy 70's sci-fi paperback. The discrepancy reminds me of C.S. Lewis' Space Trilogy: “But Ransom, as time wore on, became aware of another and more spiritual cause for his progressive lightening and exultation of heart. A nightmare, long engendered in the modern mind by the mythology that follows in the wake of science, was falling off him. He had read of 'Space': at the back of hi…

While stars, planets and other astronomical objects are fascinating, you still can't deny that there is a lot of, er, space between them, so the name is justified after all...

Every time I see these wonderful pictures I wonder if the occupants of planets (or other structures) in this region look out across a vast horizon of amassed material and wonder if those distant 'holes' or 'gaps' in their view lead to something more .. some wider 'universe' of large space .. and what would their incredulity be once their explorers make it to the end of the 'large mass' (if ever) and see the great, giant hole into which we are all born. They wouldn't need rockets - they'd need incredibly long-lasting wheel-based devices, just to see what is beyond their world.

Like, do fish ever see the air above their world and wonder if there is anything more .. its just mind-boggling to think about.

If I were of a species born on one of these Pillars, I wonder if I would see the stars and all the emptiness, eventually, as anything other than an extreme abhorrence...

I compressed the full PNG via Guetzli (Google's high-quality jpg compressor) which took a couple of hours (now 15MB at 84% quality), so here it is: https://github.com/dvasdekis/images/raw/master/pillars.jpg and https://mega.nz/file/BTdWSb6b#NHK9lAtGMIr1UxabLiC174ZvJWo7KS... and https://www.mediafire.com/file/n0qjxogsp203z0w/pillars.jpg/f... The original crashed Windows when set as desktop background, but this one wor…

Anyone else noticing the fairly common circularish structures in the top left of the image? It's like an uncanny number of stars are placed in circular arrangements. Is this due to some gravitational lensing effects around some of the objects in that area (some of which are visible)?

I'd just like to say I appreciate you for providing a diverse selection of file lockers. Thank you fair stranger.

Depends on when you would see it. Because of inflation the color of things far away is shifting to longer wavelengths so they become invisible later in the timeline of the universe (invisible to humans).

The subject of this particular image is part of the Eagle Nebula in our own galaxy. So it's near enough to be gravitationally bound and not subject to the redshift of cosmic inflation.

Is it possible to calculate how much redshift it has had relative to us from the beginning (or at any point?)?

Is it possible to visualize how a human eye would see Pillars of Creation in real time? This always confused me with Hubble’s colorized photos.

Here's a stacked series of exposures adding up to 36 minutes of the Eagle nebula (of which Pillars of Creation is a zoomed in segment) https://noctilove.co.uk/portfolio/m16-eagle-nebula/ About what you'd see from a 16 inch telescope in a superb dark sky location. A red smudge with hints of finer detail.

Thank you. If I was in a spaceship at a much closer distance to the object than I am right now, would I be able to see the dust and the shape similar to what we see on the photos? Or is this all invisible to the human eye?

Rotate the camera and bit and take another photo?

>Rotate the camera a bit Not that easy if "the camera" is JWST.

What we need is 2 JWST that can compensate for each other.

Why build one when you can have two at twice the price?
