“In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with Annie.[Dedication to Sagan's wife, Ann Druyan, in Cosmos]”

American astronomer and science communicator of the mid-to-late 20th century, Carl Sagan made complex cosmic concepts accessible to the public through his books and television series. He championed scientific skepticism and the search for extraterrestrial life, blending rigor with poetic clarity to inspire wonder about humanity’s place in the universe.
