Justin Cowart is a geologist and amateur astronomer living in Carbondale, IL. Justin has had a lifelong interest in exploring space, and one of the most fun ways to satisfy that curiosity has been looking at the images returned by space missions. His interests lie in reprocessing old data (which looks surprisingly good when it's run through modern computers!) and finding aesthetically-pleasing images that may not have gotten noticed otherwise. He can be found on Twitter as @jccwrt, and on Flickr.
This image shows the complex swirl of clouds created by the jet stream at the southern boundary of Jupiter's South Equatorial Belt. Small convective clouds bubble out of an eddy structure in the South Equatorial Belt. More widespread convective clouds dot the South Tropical Zone at bottom. The Juno spacecraft captured this image during its sixth perijove flyby on May 19, 2017.
The Juno spacecraft captured this view of turbulent clouds in the region of the jet stream marking the southern boundary of Jupiter's South Equatorial Belt. An eddy seems to be encouraging convection, with numerous clouds bubbling through the main cloud deck. This image was taken during Juno's sixth perijove flyby on May 19, 2017.
Cassini ISS view of Titan during the T-99 flyby on March 6, 2014. This 9-frame mosaic focuses on lakes around Titan's North Pole, and was intended to help map a large portion of the northern hemisphere that was mapped at much lower resolution previously. The frames was acquired at a range of 314,000 km.
