"Look again at that dot. That's here. That's home. That's us." - Carl Sagan. The popular name of this image is traced to the title of the 1994 book by Voyager imaging scientist Carl Sagan, who originated the idea of using Voyager's cameras to image the distant Earth and played a critical role in enabling the family portrait images to be taken.

Celebrating its's 30th Aniversary, NASA's Jet Propulsion Laboratory published a new version of the image popularly known as the 'Pale Blue Dot.' Planet Earth is visible as a bright blue pixel in the vastness of space. The updated version of the image uses modern image-processing software and techniques to 'revisit' the well-known Voyager 1 view while attempting to respect the original data and intent of those who planned the images.

The view was obtained on 14th February 1990, just minutes before Voyager 1's cameras were intentionally powered off to conserve power and because the probe, along with its sibling, Voyager 2, would not be able to make close flybys of any other objects during their lifetimes.

Both Voyager 1 and Voyager 2 have reached "Interstellar space" and are currently continuing their unique journey through the Universe.
