This UFO was found on some recently published photos of Comet 67P by the ESA. In the photo is a white disk. This disk is metallic, but due to the high reflective surface of the disk it appears white. This disk is also throwing a shade on the surface of the comet. Note that the shadow of the UFO is longer and stretched out, because of the slanted angle of the ground to the UFO. The shadow size and angle match. There is a also an alien face...defiantly not handsome in human terms, but nevertheless a face of one alien species. So now we know, this is why Rosetta satellite was sent to Comet 67P, to see if it can retrieve some alien tech. SCW
