Shadow of agas cloud detected in an ancient proto-supercluster
The Suprime-Cam on the Subaru Telescope has been used to create the most-extensive map of neutral hydrogen gas in the early universe. This cloud appears widely spread out across 160 million light-years in and around a structure called the proto-supercluster. It is the largest structure in the distant universe, and existed some 11.5 billion years ago. Such a huge gas cloud is extremely valuable for studying large-scale structure formation and the evolution of galaxies from gas in the early universe, and merits further investigation.

The Splitting of the Dunes
The mound in the center of this Mars Reconnaissance Orbiter image appears to have blocked the path of the dunes as they marched south (north is to the left in this image) across the scene. Smaller dunes run perpendicular to some of the larger-scale dunes, probably indicating a shift in wind directions in this area.
