The Most Inspirational Social Media I've Ever Seen.

Every so often, a good friend sends you a story, an article, or a video in this case, that not only gives you hope and inspires you, it knocks your social media socks off. I know this will go viral (259,000 views since Sunday). It's not funny, there's no vitriol, just Carl Sagan talking to us over some magnificent images of our world from Reid Gower with Michael Marantz playing piano. Bravo NASA!
