I LOVE these pictures. I first learned of them a few years ago and promptly printed and laminated a set for my classroom. I was reminded of them recently when I received them as an email attachment.
I think the art is beautiful and I can just stare at them-my mind spinning, trying to comprehend the size of the universe, all the while.
I don't know the source for these pictures. If someone out there does, please let me know and I will gladly add it.
