Yesterday was the eleventh anniversary of the death of Carl Sagan, astronomer and host of the TV show Cosmos.
I grew up watching Carl Sagan on Cosmos and spending many frozen winter nights looking at distant stars and planets through a telescope. His pop culture appeal helped bring an appreciation of astronomy to a generation who would grow up with space shuttle launches and images from the Hubble Space Telescope.
Sagan is memorialized on the planet Mars, where the landing site of the first Mars rover bears his name. Sadly, Sagan died before the first amazing images from that mission were transmitted back to Earth.
I found this video narrated by Carl Sagan where he talks about Earth as the "Pale Blue Dot" and featuring music by Vangelis.
Blogger Joel Schlosberg has posted a vast number of links about Sagan's life.
Bad Astronomy's Phil Plait remembers Carl Sagan and what he learned from him.
