Today would have been Carl Sagan's 84th birthday. I wish he were here.
Watch the above, climb aboard your Ship of the Imagination, and make the future.

My dear wonderful dad would be 84 today. I find that very hard to imagine. I spend a lot of time wondering what he would be like as an old man. I wish I could know that version of him. Just as I wish I could know the version of him pictured here, young and full of promise. I miss all the versions of him. The ones I knew and the ones I didn't. Thank you to everyone who knew him and everyone who didn't who still misses him, who still reads his work, who still thinks of him. It means a lot. #carlsaganday
We're celebrating #CarlSagan's birthday by sharing his "lost lecture", the talk he gave at his 60th birthday symposium @Cornell @CornellCAS. Today is the perfect day to celebrate the #CarlSagan vision, which inspired @CSInst https://t.co/lxvgKQEvL5
