Astronomy is said to be a humbling profession. The universe is estimated to be 13.7 billion years old and 156 billion light years wide. As of 2006, the observable universe is thought to contain about 7 × 10^22 stars, organized in about 100 billion galaxies, which themselves form clusters and superclusters. The number of galaxies may be even larger, based on the Hubble Deep Field observed with the Hubble Space Telescope. The Hubble Space Telescope has discovered galaxies which are over 13 billion light years from Earth. I am a little upset because I just broke my watch band which is about 1 inch wide.

Here is an awe-inspiring article where world-renowned astronomer Carl Sagan reacts to a photo shot by Voyager 1 in 1990. I hope you enjoy it.
