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.)

Io is the most volcanic world in our solar system, thanks to heat generated by the close tug of Jupiter's massive gravity. Of
Jupiter's four large moons, Io orbits closest to the planet, allowing it to cast a vast shadow on the gas giant.
NASA's Juno spacecraft has been orbiting Jupiter for more than three years, making a close approach every 53 days. Scientifically, the spacecraft's priorities are a host of instruments that are designed to study the planet's atmosphere and interior.
