Dunes of Mars
via nasa.gov
From the NASA website:
Dunes of sand-sized materials have been trapped on the floors of many Martian craters. This is one example, from a crater in Noachis Terra, west of the giant Hellas impact basin. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured this view on Dec. 28, 2009.
The dunes here are linear, thought to be due to shifting wind directions. In places, each dune is remarkably similar to adjacent dunes, including a reddish (or dust colored) band on northeast-facing slopes. Large angular boulders litter the floor between dunes.

Peek-a-moon
Amazing photograph of a moon rising from behind another moon -- in this case, Saturn's moon Rhea rising behind the moon Titan.
Incidentally, there will be a "blue moon" on New Year's Eve. There will not be another New Year's Eve blue moon until 2028.

Spacewalking astronauts seen with a backyard telescope

This is amazing! The spacewalk referred here took place in March 2009. Apparently someone with a telescope and a high quality camera was able to take images of the astronauts themselves.
