James Webb telescope is great and all, but I have to say I think the older image is more stunning and more aesthetically pleasing. Cleaner, simpler, nicer colors, more mysterious looking.

#42Is there some limit on the number of pictures the Webb Telescope can take in a day? Every time I see a picture from it, I just want more.
Depends on the image I think, shutterspeed can easily be a few hours

Get all those stars and galaxies out of my dust and gas photography!

#44Imagine the civilizations that live between these pillars.
Can they live in the pillars?

#45I understand Nebulae like the Eagle Nebula are fairly dynamic regions of space, so I find it interesting that we have photographs of the same region over a 27 years time span and at a glance, the structure of the Pillars of Creation appears virtually identical. I understand that 27 years is minuscule on the cosmic timescale, but what order of timescale would be necessary for the evolution of Pillars of Creation to be…
A bit more cosmic scale that we can see over time are light echos: https://en.wikipedia.org/wiki/Light_echo In particular, the at https://en.wikipedia.org/wiki/V838_Monocerotis there's a video of the echo. For another dynamic area with things changing on a human lifespan, the black hole at the center of the galaxy we can watch stars orbit it. https://youtu.be/XA7CAVm31z0
The classic example of this is the Hubble Variable Nebula. See https://en.wikipedia.org/wiki/NGC_2261 and https://www.youtube.com/watch?v=LeiVERr2J2Q

#46Also look at the comparison to the Hubble image. https://www.nasa.gov/sites/default/files/thumbnails/image/st... Impressive to see the infrared spectrum seeing through all the background gas to the millions of stars.
I think they’re millions of galaxies, which is even more amazing

#47Why are so many low magnitude stars in this image, not shrouded by gas, not visible at all in the previous image? Surely some visible light must be emitted by these?

#48Would it be possible for them to algorithmically remove the lens artifacts? I suppose just "anything with hexagonal symmetry gets deleted". They're kinda pretty but it's sad to think that this isn't what it would actually look like if you had really good infrared eyes.

#49When I go outside I can barely see any stars, unlike my ancestors who saw a sky utterly filled with stars. Then I go on my computer and I can see more stars, with more details, than my ancestors even imagined. I can't decide if it's a worthwhile tradeoff.
That's sad but understandable. The night sky where I grew up is but a fraction of what was visible as a child.
Take a trip outside of well-lit areas if possible. See https://www.darksky.org/ to find a truly "dark" location.

Interesting- If you look closely at the super bright objects, there are both hexagonally symmetric artifacts and cardinal up/down/left/right artifacts. I’d love to hear from someone with knowledge of how these arise and what optical tradeoffs prevent designs from eliminating them.
