Cosmos
Sagan’s 1980 series Cosmos reached hundreds of millions of viewers, carrying them from the Big Bang to the edge of the galaxy with infectious wonder. The companion book was a best-seller, and it was only one of many: he won the Pulitzer Prize for The Dragons of Eden, wrote the novel Contact that became a Hollywood film, and in Pale Blue Dot reflected on Earth seen from the void.
Scientist and author
Behind the broadcasts was real science — Sagan worked on NASA’s planetary missions and championed the search for life beyond Earth from the United States. Like Stephen Hawking after him, this astronomer of the modern era proved that a researcher could also be a great writer — and reminded us that we are all “made of star-stuff.”

Legacy
He remains the model of the scientist-communicator, his phrase 'we are made of star-stuff' and his 'Pale Blue Dot' reflection part of popular culture.
