NASA reveals photo of Earth from four billion miles away

NASA has released an updated version of a photo of Earth from four billion miles away.

Also known as the "Pale Blue Dot" photo, the image is now 30 years old and NASA is celebrating the milestone with the release of this new remastered version.

The image, which shows Earth as an extremely tiny, pale-colored pixel in the universe, was taken by NASA's Voyager probe.

Carl Sagan and Carolyn Porco were two of the imaging scientists who had been working on the Voyager mission. They were responsible for the Voyager taking the picture before it shut down the cameras to conserve power.

According to NASA, the Voyager took 60 photos in order to create a "solar system family portrait."

It is has been reported that Sagan emphasized the importance of taking the picture.

Sagan insisted it was necessary to have a visual representation of how tiny Earth is relative to the entire universe.

Fortunately, Sagan managed to successfully convince his team, and the Pale Blue Dot image was captured.

NASA says of the updated Pale Blue Dot image:

"The updated image uses modern image-processing software and techniques while respecting the intent of those who planned the image. Like the original, the new color view shows Planet Earth as a single, bright blue pixel in the vastness of space. Rays of sunlight scattered within the camera optics stretch across the scene, one of which happens to have intersected dramatically with Earth.

The view was obtained on Feb. 14, 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 make close flybys of any other objects during their lifetimes. Shutting down instruments and other systems on the two Voyager spacecraft has been a gradual and ongoing process that has helped enable their longevity."
