For almost 200 years humans have been watching the Great Red Spot (GRS) on Jupiter and wondering what’s behind it. Thanks to NASA’s Juno mission, we’ve been getting better and better looks at it. New images from JunoCam reveal some of the deeper detail in our Solar System’s longest-lived storm.
JunoCam is the visible light instrument onboard NASA’s Juno mission to Jupiter. It’s not part of the Juno spacecraft’s primary scientific payload. It was included in the mission just to engage and thrill us, and it hasn’t disappointed. But as it turns out, JunoCam’s high-resolution images are serving a scientific purpose.
A new study led by Agustín Sánchez-Lavega (University of the Basque Country, Spain) has used the detailed images from JunoCam to look more closely at the morphology of the clouds that make up the GRS. Up until now most of what we know about the GRS has come from previous missions to Jupiter. First were the Voyager missions, then the Galileo mission, and of course the Hubble Space Telescope. The image resolution of each succeeding mission has improved, but nothing close to JunoCam’s resolution.
