Webb vs Hubble on the Pillers of Creation - Ombligo - 10-20-2022
The iconic 2014 Hubble image of the Pillers of Creation is on the left, the Webb telescope image of the same is on the right. The birthplace of stars is in the Eagle Nebula, about 6500 light-years away.

Hard to believe the Hubble image could be replaced with a photograph even more grand, but there it is. That said, I find them both to have their appeal.

IIRC, Hubble is visible light, so the dust clouds hide much of the stellar nursery. JWST uses infrared (IR) wavelengths and can 'see' through dust.

I always wonder how much different it would look in the sky if one lived on a planet in that area of space.

I imagine that there are more than three dimensions that we are seeing.

I do not know why it is so difficult to find information on color mapping of those images. Not impossible, but difficult. At any rate, the colors are very much remapped/exaggerated in order to increase the contrast and wavelengths emitted by various elements.

If you want the REALLY deep-dive version, you can download the raw image data yourself.

WHat we are seeing now is a what occurred 6500 years ago. It's mind boggling to contemplate.

so that occurred around 4500 B.C. What was a Friday night like then? Humans were learning how to use the plow. Copper and bronze metallurgy were being to be developed. 4,242 B.C. was the very first year on the Egyptian calendar. The wheel is invented circa 4000 B.C., when those images had already been on the way for 500 years (the difference between today and Hernan Cortes overthrowing the Aztecs).
