Carl Sagan died eleven years ago today. His enthusiasm for the universe and everything in it was contagious and he is responsible for the sense of awe I and many, many others feel when we look up at the stars at night.

Our brains are not capable of comprehending the true vastness of space but Carl managed to help us expand our comprehension to the point of vertigo and, with it, and closer understanding of our true standing within the universe.

My thoughts are with his family and I, like many others, wish he was still here.
