Objects from the Oort Cloud Two tailless “Manx” comets, C/2013 P2 (left) and C/2014
S3 (center), taken with the Gemini North 8-meter telescope and the Canada-France-Hawaii Telescope, respectively. Compare with the bright tail in the image of comet Hale-Bopp (right), taken at roughly the same distance. The Manx comets could be composed of fresh Earth-building material from the inner Solar System, preserved in the distant Oort cloud. K. Meech, O. Hainaut, and J. Bauer
