M74 on Hubblecast

Over at Will Gater's blog, Will mentions the latest Hubblecast about the grand design spiral galaxy M74. Will actually had a hand in this one as he co-wrote the script for it!

It's a good video with image zooming possibly influenced by Apple's iPhone interface. I appreciated the inclusion of the information about spiral density waves which I've blogged about before and even illustrated with an image of similar grand design spiral galaxy M51. Nearer the end of the video they include M74 and M51 side by side. M74 is a clockwise spiral and M51 is anti-clockwise which which immediately made me think of the excellent Galaxy Zoo.
