As amateur astronomers well know, there's only so much you can see in visible light.

This image by the Atacama Large Millimeter/submillimeter Array was captured using radio waves and shows what's going on beneath Jupiter's stormy atmosphere.

The view shows 50km below Jupiter's visible ammonia cloud deck.

Dark bands correspond to the zones on Jupiter that are often white in visible light, while the bright bands correspond to brown belts on the planet.

The image was captured a few days after an eruption in Jupiter's South Equatorial Belt in January 2017.
