Title: View of chains of star sand dunes in eastern Algeria from Skylab
Description:
A north-looking oblique view of chains of star sand dunes in eastern
Algeria  (30.0N, 5.0E) as seen from the Skylab space station in Earth
orbit. The low  sun angle of about 25 degrees above horizontal enhances the
detail in this  picture. The field of view at the base of the photograph is
approximately 200  kilometers (125 miles). The individual dunes are roughly
star-shaped rather  than simple crescents which are common in dune fields.
In this region the  stars are aligned along ridges.
