Best photos, images, videos of Comet ISON

Professional astronomers with big telescopes have been capturing Comet ISON’s image since late 2012. Amateur astronomers with smaller telescopes joined the fun beginning in August 2013. Then, thanks to outbursts from the comet in November 2013, ISON became visible to the eye alone in dark skies, and many captured it against a background of visible stars. Now ISON cannot be seen from Earth, but it’s coming into the field of view of a whole fleet of ESA and NASA space-based observatories. We’ll continue adding to this gallery as the weeks pass.

Of course, the telescopic view of Comet ISON remains glorious. This negative - from a photo taken November 15, 2013 by Damian Peach - shows a huge amount of detail, visible after Comet ISON underwent its outburst in mid-November. Photo used with permission. Thank you, Damian!

This beauty also came after Comet ISON’s mid-November outburst. It’s from our friend Scott MacNeill, from November 15, 2013. Notice the bright, round appearance of the comet’s coma – the fuzzy area surrounding its nucleus or core – in contrast to the photo below, which was taken some days earlier. Thank you, Scott!
Michael Jager of Jauerling, Austria captured this image of the comet on November 10, 2013. It clearly shows that the comet, as it has approached the sun, has two tails: an ion tail (composed of ionized gas molecules) and a dust tail (created by bits of dirt that have come off the comet's nucleus). The ion tail points directly away from the sun, but the dust tail doesn't. That is why you see the two tails as separate. Image via Michael Jager. Used with permission.

Another great shot of Comet ISON, this one from September 28, 2013. Note the greenish color. As it nears the sun, the comet is becoming more active. Jets beginning to spew more vigorously from the comet’s nucleus contain both cyanogen and diatomic carbon, which both glow green when illuminated by strong sunlight. Photo by Michael Jaeger.

View larger. | Van Macatee captured about 100 frames at Comet ISON's location on the sky's dome, on September 14, 2013. Of those, he said, 10 showed the comet reasonably well. He then stacked the 10 good frames to compose this image.
View larger. | Van Macatee captured this image of the comet on September 14, 2013. He wrote, “I set up to shoot about 4 a.m. and captured about 100 frames. Of those, 10 showed the comet reasonably well. Before those 10 frames it was too low in the horizon haze. After those 10, the sky was becoming too light. The 10 good frames were stacked, dark and bias frames removed and stretched in Nebulosity. The image was finished in Photoshop Elements 11.”

Comet ISON recovery photo August 2013. The comet was behind the sun as seen from Earth in June, July and part of August. Amateur astronomer Bruce Gary in Arizona became the first person to spot it again on August 12. The faintness of ISON when it emerged from the sun’s glare in August dampened the early enthusiasm for this comet. Image by Bruce Gary. Full story of recovery here.
