"That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives." —Carl Sagan

Voyager 1 captured the "Pale Blue Dot" image #OTD in 1990.

The Pale Blue Dot was just one frame from a mosaic of 60 images recorded by the Voyager 1 cameras #OTD in 1990. Earth, Venus, Jupiter, Saturn, Uranus and Neptune are all visible, though Earth and Venus were each just a fraction of a pixel.

A few years ago JPL engineer @kevinmgill, with input from Candy Hansen and William Kosmann, used modern techniques to process the original image data and produce a new version of the iconic photo.

Each year on this day @Gargron should make every "." in a post render as a little pale blue dot.
Roses are red
The dot is pale blue
Here's a mote of dust suspended in a sunbeam
Seen from a distance of 40 AU
@mcnees Receders are red
Approachers are blue
That's how the spectra change
When it's galaxies you view
@mcnees
Roses Are red
On our planet place
But who knows if that
Is the same out in space
@mcnees yep, i’m a quiet peace lovin’ human on a pale blue dot…sharing it with some people with dot-sized attitudes, unfortunately…
