NASA's Juno mission has provided new data showing winds beneath the surface of Jupiter and its moon Io.
Using Juno's microwave radiometer (MWR), the mission team discovered evidence of still-warm magma below Io's cooled crust.
Juno also measured Jupiter's atmospheric temperature and found the north polar cap to be about 11°C cooler than surrounding areas with winds exceeding 160 km/h.
The spacecraft tracked massive cyclones on Jupiter, including a central cyclone at the north pole and eight surrounding cyclones that interact and oscillate around the pole.
