NASA’s Juno spacecraft is revealing the massive structure of Jupiter’s iconic Great Red Spot, a gargantuan storm that’s been raging on the gas giant for centuries. By passing over the circular storm a couple times, Juno helped scientists confirm that the spot doesn’t just exist on the upper surface but extends hundreds of miles into the planet itself.
We’ve long known just how great the Great Red Spot is. The storm’s diameter is about 10,000 miles, or more than 16,000 kilometers, wide, meaning that our planet Earth could fit completely inside the wild tempest. But scientists never fully understood how deep the Great Red Spot was. Was it just a surface-level event, or did it reach deep into Jupiter?
Now, thanks to two science instruments…
