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.Unless otherwise specified, the work of Cowart is shared on planetary.org under a Creative Commons Attribution 3.0 Unported License.

Ever wanted to stand on Mars and watch a sunset? Unfortunately for many of us, it will never be something that we get to experience in person. But thanks to our robotic emissaries on Mars, and some careful processing of images from NASA's Planetary Data System, we can get a sense of what it’s like.

This Voyager 2 Narrow Angle Camera image of Neptune was taken on August 20, 1989 as the spacecraft approached the planet for a flyby on August 25. The Great Dark Spot, flanked by cirrus clouds, is at center. A smaller dark storm, Dark Spot Jr., is rotating into view at bottom left. Additionally, a patch of white cirrus clouds to its north, named "Scooter" for its rapid motion relative to other features, is visible. This image was constructed using orange, green and synthetic violet (50/50 blend of green filter and UV filter images) taken between 626 and 643 UT.
