Cyanide anions exist in interstellar space, but the vibrationally or electronically excited states above the electron autodetachment threshold of CN- are assumed to have no contributions to cosmic CN-. Here, the authors report long-lived, superexcited CN- from the dissociative electron attachment to cyanogen bromide.
