In 1977, just a few months after Voyager 1 and 2 began their grand tour of the solar system, Carl Sagan gave the esteemed Christmas Lectures at the Royal Institution of Great Britain.

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

The Pale Blue Dot was made as a tribute to Carl Sagan "as the final project for the Animation 01 course at Ringling College of Art and Design." Read the rest “Cool collaborative student animation of Sagan's "The Pale Blue Dot" speech”

Apple released this lovely new commercial featuring Carl Sagan reading from his magnificent 1994 book Pale Blue Dot: A Vision of the Human Future in Space, now available as an audiobook. This surprising partnership spurred Adweek to interview my friend Ann Druyan, Sagan's wife, collaborator, and creative director of the Voyager Golden Record, about being the "keeper of (Carl's) flame," her own work, and the politics of science. As always, Annie is profoundly eloquent and inspiring. From Adweek:

It feels like science has been so embattled recently, that just being a scientist, just advocating for science has become a political stance in a way that it wouldn’t have been, say, six years ago.

That’s a really good point, but it’s also true there are perturbations. The pendulum swings back and forth.There are moments when science is considered heroic.

A good example from my point of view is that I was completely opposed to the war against Vietnam and to the institutional and social racism of the 1960s and generally America’s conduct throughout the world, and yet when we landed on the moon, I was proud to be an American. Even though I knew how complicated the road to the moon had been in terms of international politics and competition in the nuclear arms race, I thought this mythic accomplishment was something that really spoke well of us. It was a rare moment for human self-esteem and American self-esteem at that time.

Think back to the 1920s and Charles Darwin on trial, and you can say it was really a political statement to believe in modern biology and be a biologist at that time.

"A literal reading of the Bible simply is a mistake; I mean it’s just wrong," Sagan told Studs Terkel in 1985. (Blank on Blank)

In celebration of the new Cosmos: A Spacetime Odyssey, Joel Achenbach wrote a feature for Smithsonian about Carl Sagan's enduring impact on the popularization of science. Achenbach visited the recently-available Sagan archive at the Library of Congress and highlighted some great bits, including details of Sagan and astronomer Frank Drake's 1974 visit with bOING bOING patron saint Timothy Leary while Tim was incarcerated. Sagan had enjoyed Tim's excellent (and now scarce) book Terra II, a philosophical manual for space migration. Read the rest “Carl Sagan and Timothy Leary”
