Planetary nebula NGC 6881 lies in the constellation of Cygnus. Its "wings" spread across about one light-year.
A dying star about 60% of the mass of the sun lies at the core of the NGC 6881.
A planetary nebula arises when a dying star, a red giant, flings off its outer layers.
Planetary nebulas were misnamed by early discoverers, who thought the objects were giant planets.
