The nebula is illuminated by a young star called V* PV Cephei, or PV Cep, the bright spot at the edge of GM 1-29. It is a favorite target for amateur astronomers because the fan-shaped nebulosity changes over a timescale of months. The brightness of the star has also varied over time.
Images of PV Cep taken in 1952 showed a nebulous streak, similar to a comet’s tail. However, these had vanished when ...
