There's a tiny blue dot on the bottom left part inside the planet. Is that one of Jupiter's moons? Checkout the JunoCam page for more images: https://www.missi

  Could just be from radiation, next to Jupiter is full of 'unpleasantness'.

  Don't think so. There's a similar coloured dot around about the "10 o'clock" position near a white cloud. Probably a digital artifact, and/or possibly from high-energy particle. Edit - also the uniform turquoise colour is not very much like any known Jupiter moons. Io is sulphurous and most others are shades of grey. Titan around Saturn is one of the rare moons with a thick and colourful atmosphere.

  The blue dot is more likely an artifact of the post-processing. On the NASA's version of the image [1] you can't see it. [1] https://www.missionjuno.swri.edu/junocam/processing?id=636 https://www.missionjuno.swri.edu/junocam/processing?id=636

  It's not in this image[0] which, judging from the PIA number, is either the same or a very close one (temporaly). My guess: since the one I linked has other colouring artifacts (because Juno rotates, and the camera is a luminance sensor with filter wheels for colours), the thing you spotted is probably an artifact that ocurred when trying to better align the colour channels.

Edit: in the top left region of Jupiters disc there are other, similar artifacts to the one you pointed out, which are missing from the "natural colour" image.
