Its story

28 Cygni is a hot blue B-type star that pulses irregularly along the wing of Cygnus, over a thousand light-years away. Its light —emitted near the close of the first millennium, when European monasteries were still copying manuscripts by hand— only now reaches our retinas. It lies in the luminous corridor of the Orion Arm and is typical of the Be class: wrapped in a fast-spinning disc of gas it has shed itself.
