 the highest resolution version available.

The image above is one of the best images of emerging jets (taken last November by Rosetta spacecraft). The comet above is 67P/Churyumov-Gerasimenko (Comet CG), the picture is overexposed, and when observing the image, one can see plumes of gas and dust escaping numerous places from the nucleus (occurring because it is nearing the sun and heating up). In August, the orbit on the comet will take it almost as close to the sun as the Earth is and its jet activity is expected to increase by about 100.
