A large and prominent constellation in the northern sky shaped like a swan, also containing the bright star Deneb.
From Latin 'cygnus,' meaning 'swan,' which came from Greek 'kyknos.' The constellation has been recognized since ancient times, with multiple swan-related myths attached to it across cultures.
Cygnus is home to Cygnus X-1, one of the first confirmed black holes, discovered in 1964—a swan constellation guarding a monster from which nothing, not even light, can escape!
