YouTube Saturday - Wonders of the Universe
If we were lucky enough to see the brilliant BBC series, Wonders of the Solar System, then you were treated to a fantastic collection of brilliantly structured episodes revealing the real marvels of our galaxy. Professor Brian Cox (the "rock star physicist" who looks as awed as I do when watching it) visits some of the most stunning locations on earth to describe how the laws of nature have carved natural wonders across the solar system. In this clip, he searches for evidence of liquid water on Mars. Why not check out the BBC's excellent guide to the solar system by clicking here. Incidentally, Brian Cox was also working on the ATLAS experiement with CERN. The final episode of the series is on Sunday at 9 on BBC2.
