Solar System Snapshots #5FLOTILLA OF DUNES These chevron-shaped dunes are carved by wind acting on the sandy topography in a valley called Mawrth. Acquired on December 30, 2013, this image was taken from about 287 km above the surface, with the Sun about 48° above the horizon. #6 SUNSET ON A DISTANT WORLD Imaged just after a spacecraft's flyby of this body, the prospect seen here extends across an area about 380 km wide. Backlit by an extremely far-off setting Sun, the scene displays icy plains (right) and ice mountains soaring 3,500 meters into the sky (left). The camera also captured more than a dozen layers of haze in the tenuous atmosphere. 24 JUNE 2022 * SKY & TELESCOPE #5: NASA / JPL / UNIVERSITY OF ARIZONA; #6: NASA / JOHNS HOPKINS UNIVERSITY APPLIED PHYSICS LABORATORY / SOUTHWEST RESEARCH INSTITUTE; #7: NASA / JPL
