The Jupiter moon Io - captured by the Juno spacecraft during Perijove 58.
The angle of the sun during this flyby created stunning specular reflections on the basalt covered lava lake of Loki Patera.

A small plume is visible at the limb of Io in the lower right of the image - I increased the brightness of the plume in processing to make it more visible.
Io's shadowed side is lit by Jupiter, resulting in a rather bright appearance.

I assembled the image from the raw framelets using a custom python script for calibration and PTGui for stitching.
The colors were calibrated to match how the human eye would see them using the CIE1931 color system and reference spectra from the Jovian System.

This real time animation shows how JunoCam acquires an image.

@stim3on
One can see two plumes in this very high quality processed image at full res.
👏

@AkaSci Yeah, it seems like they are two adjacent plumes. So far I have not seen which volcano they belong to.
