These come from Juno, a mission sent in 2011 and orbiting Jupiter since 2016. Must say it wasn't really on my radar anymore, but looking at the timeline on Wikipedia, it's still going around and getting close ("perijove") every month and a week or so, at an ever-increasing longitude https://en.wikipedia.org/wiki/Juno_(spacecraft)#Timeline The planned end of the mission is in about a year. The camera was "included in the payload to facilitate education and public outreach [but] later re-purposed to study the dynamics of Jupiter's clouds"
