Pale Blue Dot

In my mind the pale blue dot is the most important picture people have ever taken - when I see it it feels almost like the ground has been pulled out from under me.  I can feel my priorities and attitudes shifting, and it has become central to how I think about life.

It is also technically amazing.  Sending a picture back to earth from four billion miles away with technology that was developed fifty years ago is jaw dropping.  And the probe is still out there, sending more data.
