First full color James Webb Space Telescope pics will be released this afternoon

Hunter's dad will do the honors at 4. The White House set up a hasty press event to usurp the reveal for obvious reasons.
And yes, the pics will be either color corrected or, more likely, artificially colored because James Webb sees in infrared not in the colors of visible light.
Light from distant objects is shifted to the red side of the spectrum because the entire universe is expanding and galaxies are moving away from each other, and the expanding space increases the wavelength of light. So if the light has been redshifted enough, the color added could be just resetting the image to what the light looked like when it left the distant source but more likely the objects imaged won't be that far away/redshifted so it will just be an infrared image mapped to color.

Are you telling me that these images are gonna have fake pixels of color?

Looking forward to these.

So they are making it up

If I were the tech person setting it up, I would play the video of Hunter arguing with the hooker about how much crack is on his little digital scale instead

They'd be fired and villainized by the National media, and employed by Elon Musk by end of the day.

How amazing would it be if some patriot snuck a picture of Hunter smoking crack into the PowerPoint

If they don't add false color, the images aren't going to be anything close to what your eye would see because they are taken in the infrared.
The telescope can see a little red and orange light but otherwise it's like a thermal image photo.

Wait all this for black and white images that they add color to?

Why are we on a collision course with Andromeda given this, that's what I want to know.

They aren't all moving in the same direction.

Damn. My interest waned dramatically. I get why this is the case though, and hope the images would be color corrected as opposed to the coloring just being made up.
Artificial coloring is basically what some nerd at NASA thinks looks cool, and we have enough of those from Hubble already.

On very local scales (and 2 million light years is still considered local in the cosmic scheme), gravity still predominates.
Milky Way and Andromeda are close enough together that their mutual gravity is attracting each other on a collision course.

Locally gravity dominates so the mutual gravitational attraction has the galaxies on this course. That's why the sun, planets and moons in the solar system keep doing what they are doing, because gravity dominates in close quarters.
But on a wider scale, galaxies are far enough apart that the expansion of space is stronger and eventually will turn every galaxy or local cluster into an isolated island where nothing is visible beyond it if the expansion doesn't rip everything apart first.

No it’s being color corrected so the average person can actually understand what they’re looking at

Judging by this thread, that's a waste of time because the average person doesn't understand shite.

Stupid joe will mess it up somehow.
