Image developers on the Webb team are tasked with turning the telescope’s infrared image data into some of the most vivid views of the cosmos we’ve ever had. They assign various infrared wavelengths to colors on the visible spectrum, the familiar reds, blues, yellows, etc.
Longer infrared waves are assigned redder colors, and the shortest infrared wavelengths are assigned bluer colors. (Blue and violet light has the shortest wavelengths within the visible spectrum, while red has the longest.) The process is called chromatic ordering, and the spectrum is split into as many colors as the team needs to capture the full spectrum of light depicted in the image.
The chromatic ordering depends too on what elements are being imaged. When working with narrow-band wavelengths in optical light—oxygen, ionized hydrogen, and sulfur—the latter two both emit in red. So the hydrogen might get shifted to green visible light, in order to give the viewer more information.
When telescope images are being assembled, image processors work with instrument scientists to decide which features of a given object should be highlighted in the image: its piping hot gas, perhaps, or a cool dusty tail.
In the case of the sweeping shot of the Carina Nebula’s cosmic cliffs, different filters captured the ionized blue gas and red dust. In initial passes at the nebula image, the gas obscured the dust’s structure, scientists asked the image processing team to “tone down the gas”

The usual hyperbolic “news” article. The telescope gathers light in frequencies humans cannot see, so obviously the “images”, and even that’s an antiquated term as everything is gathered digitally, are manipulated to render a visible color value.
yep, all deep space images are colored.
I don’t mind enhancements to stuff we can’t see with the eye. The telescopes have given us insight into some pretty cool stuff, enhanced or not.
As much as it cost, TPTB have to keep the public’s interest up.
Well, it’s what you have to do to see the invisible.
Think of it as “down converting”.
Exactly.
The Carina Nebula, an enormous cloud of dust and gas 7,600 light years away, as well as the Southern Ring Nebula, which surrounds a dying star 2,000 light years away.
Carina Nebula is famous for its towering pillars that include “Mystic Mountain,” a three-light-year-tall cosmic pinnacle captured in an iconic image by Hubble.

This freeper has been saying this for years now. 95% artist enhancement, 5% true data.
I am always struck by how the macrocosm and the microcosm can seem similar. These kind of nebula and star pictures remind me of the appearance of the amniotic sac around a preborn child.
The images are not invisible. Your eye cannot detect energy in the infrared…. The instruments on the other hand are designed for that purpose
Indeed
Wouldn’t have cost that much had they not kept changing the specs
The whole point of any telescope is to see beyond.
Some folks are just never satisfied. No vision!
“James” = Ya’akov. It’s a ginormous weBB of intel.
2B or not 2B, that is the question.

Assignment of various infrared wavelengths to colors on the visible spectrum allows humans to "see" what the optical senors detect and can analyze for a better understanding of the cosmos and cosmic events.
While computers and sensors use that data to test the Theories that Scientists and Researchers develop, everyone can "see" the data that is invisible.
