Kevin Milne: The Pale Blue Dot - a thought provoking image - Saturday Morning with Jack Tame

A picture is worth a thousand words, or so the saying goes. 

Images often convey more meaning and information than can be held in a sentence or two, an image often provoking more emotion or deeper thought. 

Kevin Milne saw one such image earlier this week – an image of the Earth, taken in 1990, from 6 billion kilometres away: The Pale Blue Dot.
