Io's shadow ...

Don't panic, this isn't a massive hole on Jupiter.

All is well on our largest neighbor; NASA's Juno spacecraft just managed to spot the shadow of Jupiter's moon, Io, passing over its marbled clouds.

The Juno mission made its 22nd close skim over the gas giant around Sept. 11, when the celestial geometry was just right for Io to slip between the sun and the planet during one of its rapid-fire circuits of Jupiter. (The moon takes just 1.77 days to orbit the planet.)

This is an imperfect experiment to create a 360˚ horizon-to-horizon view over Jupiter during Juno's Perijove 22 flyover of Io's shadow. https://www.youtube.com/watch?v=NX1SYot-1vc

Cool without question.
