In early May 2013, the position of comet C/2011 L4 (PanSTARRS) was quite close to the emission nebula NGC 7822 (shown along the bottom of the image) and planetary nebula Abell 1 (the small blue gem at the upper left), in the constellation Cepheus. A very unique feature of this image is that it contains one red object (NGC 7822), one green object (the comet), and one blue object (Abell 1). This is interesting because red-green-blue (RGB) is the nearly ubiquitous color space used in digital color images. Comets are essentially the only green objects in the universe (and they move quickly), so it is very uncommon to find red-green-blue objects in the same frame.
