Anomalously bright features were found at the north and south poles. The north polar feature is oblong (4\u00b0 by 8\u00b0) and offset from the pole. The smaller south polar feature is mostly confined to the floor of the crater Chao Meng-Fu. The polar locations and radar properties of these features indicate that they may be produced by volume scattering in ice. The images also reveal a variety of more subdued reflectivity features ranging in size from hundreds to thousands of kilometers; some of these appear to have an impact origin.<\/p>\n<p><!-- Link: <a href=\"http:\/\/science.sciencemag.org\/content\/258\/5082\/640\">http:\/\/science.sciencemag.org\/content\/258\/5082\/640<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A random-code technique has been used at Arecibo to obtain delay-Doppler radar images of the full disk of Mercury.
