haha anus ur anus so huge we need a 10 billion dollar space telescope to see it

fr tho: JWST NIRCam image of Uranus enabling us to see it's rings. The blue of the photo makes me think I bunged up and this is actually a MIRI image. deal w/it

What did you just call me?!

A space telescope! Deal.

The colors are all always false colors added in post processing (maybe I'm wrong?? Someone please correct me if I am), so I think you're good

False colours yes but added by educated guesses (I think). MIRI pictures also always have the blue-ish tinges to them.

I thought that they don't necessarily aim for a guess at true color but instead for coloration that conveys the most detail. Again, would love to know if I'm wrong. Also I think the JWST images are not exactly "official" but open submission because everyone and anyone can not only access the data for processing into an image (outside of an exclusion window to allow people to write research papers) but also request where the telescope is pointed.

Edit: it probably depends. This being a planet, it might make sense to stick to true visible light coloring but nebula and galaxies might not matter as much

Most of JWST's wavelength range falls in the infrared, only overlapping the red end of the visible spectrum. That means basically all its images are in false color, showing infrared wavelengths as visible ones. I'd be surprised if any are true color images considering how boring they'd be (just some deep reds and oranges).
