Solving Approach
Words in this cipher average roughly 3.7 letters apiece. Short words are common here, so scan for one- and two-letter groups first; they narrow the alphabet fast. At medium difficulty, expect to lean on letter frequency and word patterns rather than a single obvious giveaway.
About Carl Sagan
Carl Sagan was an American astronomer and science communicator who became famous for making complex cosmic concepts accessible to millions through his iconic television series Cosmos. He championed critical thinking and the scientific method while warning against pseudoscience, famously coining the phrase "extraordinary claims require extraordinary evidence." Sagan's passionate advocacy for space exploration and his poetic reflections on humanity's place in the universe inspired generations to look skyward with wonder and curiosity.
Did you know? Sagan played a key role in the Voyager Golden Record project, which placed sounds and images of Earth aboard the Voyager spacecraft to communicate with potential extraterrestrial life.
