A big storm, by definition, on mighty Jupiter

Citizen scientists process a stunning image of a giant storm in Jupiter’s northern hemisphere taken by NASA’s Juno spacecraft during its 11th close flyby of the giant planet. Bright cloud tops look similar to storm clouds on Earth, although the scale is vastly larger. Juno is giving planetary scientists a unique view of Jupiter from the spacecraft’s polar orbit.

The intensive survey was a unique collaboration between astronomers and “citizen scientists,” volunteers who provided invaluable help in analysing the mountain of data from Hubble.
