On Feb. 14, 1990, famed scientist Carl Sagan gave us an incredible perspective on our home planet that had never been seen before.

As NASA’s Voyager 1 spacecraft was about to leave our Solar System in 1989, Sagan, who was a member of the mission’s imaging team, pleaded with officials to turn the camera around to take one last look back at Earth before the spaceship left our solar system.

The resulting image, with the Earth as a speck less than 0.12 pixels in size, became known as “the pale blue dot.”
