Hartley 2, an Unusually Hyperactive Comet (2 of 2) (IMAGE)
Caption
(A) Hartley 2, image mv6000002, ~ 7 m pixel–1. Sun is to the right, and the positive rotational pole is at the smaller (right) end. The view is from latitude ~ –33°. (B) Relatively smooth region of larger lobe. (C) The waist between the two lobes. (D) Knobby terrain, characterized by rounded to angular elevated forms up to 50 m high and 80 m wide. (E) An example of a roughly equidimensional spot < 80 m across that appears even darker than the larger, more elongated “dark” areas. For more information, please see Figure 3 in the manuscript. This image relates to an article that appeared in the June 17, 2011, issue of Science, published by AAAS. The study, by M.F. A’Hearn at University of Maryland in College Park, Md., and colleagues was titled, "EPOXI at Comet Hartley 2."
