The Jet Propulsion Laboratory of the NASA published a new version of the image of Pale Blue Dot.

Pale Blue Dot

• The ‘Pale Blue Dot’ is one of the most iconic images in the history of astronomy.
• It shows Earth as a single bright blue pixel in empty space within a strand of sun rays, some of which are scattering from and enlightening the planet.
• The original image was taken by the Voyager 1 mission spacecraft on February 14, 1990 when it was just beyond Saturn.
• At the behest of astronomer Carl Sagan, the cameras were turned towards Earth one final time to capture the image.
• After this, the cameras and other instruments on the craft were turned off to ensure its longevity.
