A composite image showcasing the evolution of Comet 17P/Holmes from October 25th to January 30th. The images reveal the comet's dramatic expansion and fading coma, and its apparent retrograde motion against the background stars as observed from Earth. The comet's size is shown to expand to over five times the size of the Sun.

A composite image showcasing the evolution of Comet 17P/Holmes from October 25th to January 30th. The images reveal the comet's dramatic brightening, coma expansion, and fading, as seen from Earth's changing perspective. The comet's apparent retrograde motion is also visible due to Earth's orbital movement.

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.
