PICTURE OF THE DAYsee all »

Comet Jacques

This image of Comet Jacques (C/2014 E2) comes from a long-time contributor. He added, “The comet changed to a beautiful teal coloration from the previous emerald green. This change was accompanied by the loss of the comet’s tenuous gas tail. This image shows the comet crossing the ultra-dense Cygnus star clouds near Albireo. We can see quite a mixture of stellar spectral types in this image as multi-hued star trails. The comet appears frozen against the moving star background in this hour-long exposure.” (12.5-inch homebuilt Newtonian reflector, SBIG ST-10XME CCD camera, 1 hour total exposure, taken September 14, 2014)
