You want to know a funny truth about photos of the planets? After the Voyager flybys, photos taken through Earth-based telescopes suddenly got a lot clearer and sharper. Once astronomers knew what the surface of the planets looked like, their images mysteriously became clearer and more precise.

Yeah, you got 'em all right, only an idiot would believe that the same technology level boost that allowed us to send interplanetary probes to the outer Solar System would also result in far better telescopic imaging, especially today's space-based telescopes that didn't exist when that first photo was taken in 1879 by Irish astronomer Agnes Mary Clerke.

I think you might be stupid. Have that checked out by a competent idiot-wrangler.

Land based planetary photographs are actually thousands of photographs taken in one night and run through a software which chooses the least atmospherically distorted photos and stacks them on top of each other enhancing the sharpness and details to an extreme degree.

Gosh do you think that computers and software might have gained any power or sophistication since before the planetary flybys? Let me go check my Commodore Pet to see how it handles large JPEGs.

They also had two extra years to advance tech.

Voyager 1 was launched on Sept 5, 1977 and encountered Jupiter March 5, 1979

I'm just gonna come out and say it... the earth is fake and gay, alright?

Mostly the Southern Hemisphere though. That's where the giant turtle is.

On a conspiracy footnote: Why does the giant storm always face Earth. Are there any pictures of Jupiter with it on the far side?

Good question. We have photos of the backside taken by satellite but can't find an explanation as to why the layperson seeminly cant find any published earth photos of Jupiter without the spot in last 400 years.

Why can't I find a picture taken from earth that is missing the red spot.

Maybe it's the only view that people like to publish.

Edit: this picture appears to be missing the red spot, taken from hubbell

...and both are fake?

Note that the original is inverted, because it was taken with a reflector telescope.

But you could just turn the camera upside down

Why is it blue? It's digital so there isn't an actual negative.

Putting it more simply than the other guy, James Webb is an infrared telescope, not a normal reflection scope like Hubble. So they take images of light not normally visible to the human eye and color them based on the intensity of the infrared in different areas to make the image make sense to your brain.

They’re not just arbitrarily coloring/doctoring the photo like some people here are suggesting; the different colors actually coordinate with specific data from each region of the planet

Their choice of color assigned to that wavelength is arbitrary, though.

Perhaps some wavelengths resemble reality.

They could closely match the wavelength if they chose to. The value in it for them is not just pretty pictures, though, so this is what we get.

The James Web photos can see the different wavelengths. nasa fills them all in with colors to help distinguish between them. It's not like the hubbel where they actually make color photos. In a way it's neat because it allows one to see all the distinctions. In a way it is sad because artificially colored and so you aren't looking at what it really looks like.

Basically, this is like what a Terminator "sees"

inverted jupiter looks pretty cool ngl

It's like a lil' face of someone groggy and upset going "don't look at me, what do you want."
