A beautiful title

Today I found one book from my bookshelf, it's title is " Pale Blue Dot " by Carl Sagan. It is got old in the bookshelf, I haven't see it for many years almost 9years . I surprised that book title is so beautiful . I didn't know how he was explaine in this word. Earth is so beautiful, but it's just dot in this universe? We are just living on the dot in the universe and life is just in second in the universe. I like to watch star in the sky sometimese with my daughter, and I feel we are watching a piece of past universe. It's realy funny....
