It’s the twentieth anniversary of the famous “pale blue dot” photo – Earth as seen from Voyager 1 while on the edge of our solar system (approximately 3,762,136,324 miles from home). Sagan’s words are always worth remembering:

I listen to ABC News Radio's astronomy show, Star Stuff by podcast every week. I recommend it.
Carl Sagan was so right about Astronomy being 'a humbling and character-building experience'. If you are regularly thinking about our 'place' in the universe then it is very hard to believe we are the apple of the supposed creator's eye. It takes millions of years for light to travel to parts of the universe where humans will never go or ever see, so this was created for what? In the grand scheme of things, we are not even a vapour, and far less than a blue dot.
Great post. Thanks.

I never tire of reading Sagan. It put's all of life's worries into perspective in an instant.
TLY, following on from your comment of our 'place' in the universe, here's something I only learned a year or two ago that adds yet another dimension to that theme...
Our solar system (to which we attach such permanence and immovability) is the detrius of a third generation of supernovae since the big bang - a third generation of gravity-powered condensation of 'star stuff'. In a few billion years, our sun will supernova, scattering a literal starburst of debris in 'our' little corner of the galaxy. The resulting cloud of pulverised mass will continue to expand until its inherent mass (gravity) slows the expansion... the expansion will again eventually reverse and become an equally inevitable contraction and so the cycle repeats for a fourth time...
We are truly 'star stuff' as Sagan used to say. Every milligram of mass in your body has (so far) been part of three different solar systems, with more solar systems to come.
Awe inspiring stuff.
