NGC 7129 is a dim nebula in the constellation Cepheus. It is remarkable in that portions of it are an emission nebula emitting light of the hydrogen-alpha wavelength. But most of it is a blue reflection nebula as a result of dust scattering blue light from stars, much as scattered sunlight in our atmosphere makes the sky blue. Still other portions of it are a dark nebula due to dust clouds obscuring what is behind them. But that is not all. The nebula exhibits several bright red Herbig-Haro objects where very young stars are still in the process of forming. The dark nebula around NGC 7129 is LDN 1181 and the dark nebula trailing off into the lower right corner of the image passing the bright blue star is LDN 1183. NGC 7129 lies 3,300 light years from Earth.
