I pointed to that page yesterday. Thread: BBC - scientists spot "strange structures" on surface of YU55 (Page 2)

NASA Releases Radar Movie of Asteroid 2005 YU55 11.08.11

"The animation reveals a number of puzzling structures on the surface that we don't yet understand. To date, we've seen less than one half of the surface, so we expect more surprises."
