“All science asks is to employ the same levels of skepticism we use in buying a used car or in judging the quality of analgesics or beer from their television commercials.”

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.
