Comet Catalina and its dusty tail can be seen in this skywatcher image. The comet C/2013 US10 (Catalina) passed the Sun last month and is approaching Earth in January.
Astrophotographer Chris Schur took this image on Dec. 2 from Payson, Arizona. "This image shows how the separation between dust and gas tails in this coming comet has changed dramatically from even a few weeks ago," Schur wrote in an email to Space.com.
In the image, Comet Catalina - also known as C/2013 US10 - is sporting both dust (lower left) and ion gas (upper left) tails. It passes closest to Earth, at a distance of 0.72 astronomical unit (108 million km) on Jan. 12 making the first weeks of the New Year an ideal time to observe this comet.

"We have great things to look forward to in the coming weeks!" Schur added.
The image was taken with 80mm f/4.6 Stellarvue, an SV80 refractor, a Canon XTi camera, set at ISO 800 with 10 mins total integration time.
