In 1990, after years of lobbying by Carl Sagan, Voyager 1 turned its camera back toward home from about 6 billion kilometres away and photographed Earth as a pale blue speck smaller than a single pixel — an image NASA had repeatedly resisted because it offered little scientific value, but that became one of the most famous photographs ever taken.
- Voyager 1 captured Earth's image from about 6 billion kilometres away, showing Earth as a pale blue speck.
- Carl Sagan pushed for the image, recognizing its value despite limited scientific data.
- The image faced practical resistance due to risks of pointing cameras near the Sun and consuming mission resources.
- NASA released a reprocessed version in 2020 for the 30th anniversary of the Pale Blue Dot.
- The Pale Blue Dot became famous not only for the image but for Sagan’s accompanying writing.
- The image has endured as a perspective-shifting symbol of Earth's smallness and humanity's place in the cosmos.
- Voyager 1 has traveled far beyond its 1990 distance, and its cameras have been off for decades.
- The Pale Blue Dot remains a lasting self-portrait of the solar system from extreme distance.
