Jupiter image

True color simulated view of Jupiter, which is not based on a single image

With the multiple photos of Jupiter we have in Commons, surely there would be a larger file that's also in true colour. Would anyone care to put in the effort for finding one since the current image's technical quality is bothering the hell out of me. _ZZ^Z'S 14:58, 25 September 2024 (UTC)

The current image quality looks good to me, and it satisfies the image criteria for planetary objects. Cf. MOS:ASTRO: "Show the article object as viewed in natural light, without enhancements of specific spectral bands or frequency shifting". Praemonitus (talk) 18:15, 25 September 2024 (UTC)

I don't think a fuzzy image with a 579 × 549 resolution and a file size of 91 KB is "good" quality. _ZZ^Z'S 18:21, 25 September 2024 (UTC)

If the current resolution is greater than the actual displayed image size, why would increasing the resolution matter? Praemonitus (talk) 05:21, 26 September 2024 (UTC)

It prevents upscaling because upscaling a PNG/JPG decreases the image quality. _ZZ^Z'S 17:43, 26 September 2024 (UTC)

Someone changed it again to New Horizon's image which shows Jupiter in false color. New Horizons lacks proper filters to establish a true color image. Only crude approximations can be made. In case of Jupiter flyby, we see there's olive-green color and that simply doesn't exist there. I changed the picture and then someone reverted the editing "because it's too small". That is not a valid criterium. A small photograph of a lion with a normal camera, would obviously be prefered to a larger, false color thermal image. Why not planets? There is a continuous annoying effort online to represent bodies of the Solar system as they don't appear. Lajoswinkler (talk) 14:18, 4 November 2024 (UTC)

I think this photo from Juno is a good alternative File:Jupiter - Perijove 21 - GRS Composite (48415785321).jpg. Artem.G (talk) 21:27, 5 November 2024 (UTC)

I don't think that'd work. It's too distorted and not very conducive to what it would actually look like from a human's point of view. The Hubble photo that recently got swapped in is far better; I don't know why I had even added the New Horizons photo there in the first place. TheWhistleGag (talk) 20:34, 12 November 2024 (UTC)

Blackbody temperature reported on this page is incorrect

The blackbody temperature of the Jupiter reported on this page is incorrect. It should be updated to 124.4+/-0.3 K. The source is here: https://ui.adsabs.harvard.edu/abs/2023RemS...15.1811R/abstract (see footnote 9 at the bottom of page 8). Not just on this page, but on all the solar system planet pages, the "blackbody temperature" should really be listed as the "effective temperature" (http://en.wiki.x.io/wiki/Effective_temperature#:~:text=The%20effective%20temperature%20of%20a%20star%20is%20the%20temperature%20of,R%20is%20the%20stellar%20radius.) or "effective blackbody temperature" because planets are not blackbodies, this is simply the effective blackbody temperature that we get when we integrated the flux over the entire spectrum. 35.6.72.204 (talk) 15:22, 21 November 2024 (UTC)

Jupiter's color

I am only 11 so correct me if my statistics are wrong. But why is Jupiter many colors mars is one color due to the sand and personally I think Jupiter needs more research and fly by done. I want to know if different materials are found on Jupiter 50.127.5.36 (talk) 16:09, 2 January 2025 (UTC)

Well your question does raise an interesting point: why does Jupiter's gaseous atmosphere possess longitudinal bands of different hues? I don't think the current article provides an explanation; it just says they exist. You don't really see that on the other gas giants (or at least not to the same degree), so I'd like to know why as well. Presumably it has something to do with internal heat and chemistry, but why the banding? Praemonitus (talk) 17:46, 2 January 2025 (UTC)

Does this article answer your question? ZergTwo (talk) 17:51, 2 January 2025 (UTC)

I think it may be close to how Mars is red, because of the chemicals and yes that does answer my question. 50.127.5.36 (talk) 18:03, 3 January 2025 (UTC)

Well, the article states that the "origin of Jupiter's colored banded structure is not completely clear", so I suppose not. Tyler (2022) proposed that the banding structure may be caused by tides, so that's a possibility.[1] Praemonitus (talk) 03:22, 4 January 2025 (UTC)

Aren't you asking why Jupiter's bands are coloured, not their origins? ZergTwo (talk) 03:56, 4 January 2025 (UTC)

Both. Presumably the two are related. Praemonitus (talk) 05:40, 4 January 2025 (UTC)
