Scientists have used cameras on the Juno spacecraft to create the first 3D map of radiation around Jupiter and its moons.
These cameras, originally designed to track stars, were repurposed to detect high-energy particles, creating a 'firefly' effect on their images.
The map revealed a surprising flow of electrons near Europa, one of Jupiter's moons, which might have an ocean beneath its icy surface.
This discovery is a big step in understanding how Jupiter's magnetic field influences its moons, helping plan for future missions to explore the possibility of life in the Jovian system.
