Happy Birthday, Carl Sagan.
If you have even a remote interest in astronomy, you know Carl Sagan. Though he passed away years ago, his words are still splashed on letterheads, his quotes still inked into the skin, and his influence still seen...floating on the outskirts of our solar system, in two golden records that are destined to be the first man-made objects to break free from the Sun's influence, allowing the discs to roam freely in the spaces between stars.
