A partial family portrait of the Jovian system, with Io, Europa and Jupiter.
This was captured by the Juno spacecraft during Perijove 58 last weekend.

Just about 20 minutes later, after making it's close approach to Io, Juno captured this image looking back at the moon from the other side.
I processed this image from the raw stripes data using a custom calibration script for dark subtraction and flat fielding (using @bswift's flatfield) and then assembled them using
@kevinmgill's JunoCam processing pipeline.

The colors were calibrated to match what the human eye would see according to the CIE1931 color system, using the spectral response curves of JunoCam as well as reference spectra from the Jovian System.
Thanks also to Björn Jónsson for helping me with the color balance, since JunoCam's color response has changed significantly over the years, likely due to the extreme radiation in the Jovian System.

The community around JunoCam is truly amazing!
