Comet Catalina (Comet C/2013 UQ4) photographed by the NEOWISE telescope

Comet Catalina (C/2013 UQ4) was originally being tracked as an asteroid but later turned out to be a comet. This latest discovery was made earlier this year by Artyom Novichonok (who also helped discover Comet ISON) and Taras Prystavski using a remote telescope in Siding Spring, Australia. Comet Catalina was closest to the Sun (at its perihelion) on July 6, 2014 and was extremely active shortly thereafter. This image was taken by NASA’s asteroid hunting NEOWISE space survey program.
