Carl Sagan's Pale Blue Dot May Help To Keep Tuesday's Presidential Election In Perspective : 13.7: Cosmos And Culture On a day where we as a nation will make a very important collective decision, Carl Sagan's speech serves to help remind us of our place in the universe, says astrophysicist Adam Frank.

So, it's Election Day here in the United States.

Every presidential election seems important, but I am sure that I am not alone in thinking this one is different, maybe more important than most.

So, please, go vote.

When you're done, I give you (once again) Carl Sagan's beautiful "Pale Blue Dot" speech to put it all in perspective.
