For today’s Video Wonder, we present Carl Sagan’s poignant “Pale Blue Dot.”

The text, originally given at a lecture at Cornell University, was inspired by a photograph taken of Earth on Valentine’s Day, 1990 from the Voyager 1 probe. In the picture, the earth and everything on it is a mere pixel, a faint blurry pinprick. This is the last photo the probe would take of our planet before drifting off into deep space.

Sagan’s speech and the video accompanying it serve as a reminder that everything good and everything terrible we know are but a minuscule portion of existence, and that there is simply much more out there.

Every day we track down a Video Wonder: an audiovisual offering that delights, inspires, and entertains. Have you encountered a video we should feature? Email
