These are what the clouds on Jupiter look up close. The small patches of white are cloud tops, soaring above the main, colourful cloud layer. Image from NASA's Juno spacecraft during its 38th close approach to Jupiter on 29 November 2021, processed by Kevin Gill (@kevinmgill.bsky.social)
A complex, swirling pattern of lighter and darker clouds. One large system, angled to the upper left in this scene, is a tawny brown colour and is elongate. Another, more circular storm system is at lower centre, and is a grey–greenish colour. The background swirls are various shades of grey to blue; small, white features dot the scene.

I'm only now learning about "vector meson dominance", a big idea put forth by Sakurai and others around 1960. Just as the pion comes in +, - and neutral forms and has spin 0, the rho meson comes in +, - and neutral forms and has spin 1 - so it's described by a "vector", like the photon. (1/n)
