Its story

68 Cygni is a rare specimen: a massive blue O-type star, one of the hottest and most luminous classes in existence, burning at tens of thousands of degrees at its surface. It belongs to Cygnus, that cross laid out across the Milky Way, and is tied to the young stellar associations populating the region. Its brightness varies slightly, an echo of the violent processes that stir blue giants.
