A composite image showcasing the apparent movement of Mars and Saturn against the backdrop of the Milky Way from mid-December 2015 to early 2016. Mars' path is a wider, S-shape, while Saturn's is a tighter loop. This apparent retrograde motion is due to Earth's orbital movement. Near Antares and the Milky Way's central bulge.
