Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
Friday, April 22nd marks Earth Day 2022, and while we’re not limiting our pledge to live a little greener to a single day a year, it marks a great opportunity to teach our kids about living ...

Voyager 1 overtakes Pioneer 10 as the most distant spacecraft from the Sun, at 69.419 AU. Voyager 1 is moving away from the Sun at over 1 AU per year faster than Pioneer 10. 2004-12-17 Passed the termination shock at 94 AU and entered the heliosheath. 2007-02-02 Terminated plasma subsystem operations. 2007-04-11 Terminated plasma subsystem heater.
Held the record for fastest human-made object at the time and the most distant one until Voyager 1 overtook in 1998. Closest approach towards Jupiter was at 02:25 UTC on 4 December 1973. Flew by Callisto, Ganymede, Europa and Io at long distances. Final signal received on 23 January 2003, 12 billion km (80 AU; 7.5 billion mi) from Earth. [5] 2
Given Voyager 1’s immense distance from Earth, it takes a radio signal about 22.5 hours to reach the probe, and another 22.5 hours for a response signal from the spacecraft to reach Earth.
This narrow-angle color image of the Earth, dubbed ‘Pale Blue Dot’, is a part of the first ever ‘portrait’ of the solar system taken by Voyager 1. From Voyager's great distance Earth is a mere point of light, less than the size of a picture element even in the narrow-angle camera.
