Cool image time! Images taken two minutes apart by Rosetta have captured the emergence of a new jet on Comet 67P/C-G.
The two images released today show the remarkable onset of such a jet for the first time. They were taken on 12 March from a distance of 75 kilometres. In the first image, obtained at 07:13 CET, several rays of dust jets frame the upper, illuminated side of the comet. The dark underside shows no such features. Two minutes later, the picture has changed: a spectacular new jet has emerged on the dark side, hurtling dust into space and displaying a clearly discernable fine structure.
This was the first jet observed in a shadowed area, and the scientists think this jet might have started because it was just before dawn there.
