Fascinating stuff.  You can leave any comments and rate the video, and join the TeamHanash channel so that you’ll hear when the next video is released.  If you haven’t already read it, Andrew Collins’ website has the story of its discovery.  Click on News and scroll down – there is plenty on it, but I’d start by scrolling down to the Earthquest News for August 2009 (vol. 12, no.2).
