A young open star cluster is responsible for illuminating the surrounding nebula. ngc 7129 is a reflection ne bula at a distance of 3,300 light years in the constellation Cepheus. NGC 7129 is a reflection nebula at a distance of 3,300 light years in the constellation Cepheus. It is about 3,000 light years away from Earth.
The dust nebula NGC 7129 in the foreground is about 3,000 light years away, while the open star cluster NGC 7142 is probably over 6,000 light years away. In fact, the widespread and clumpy dust clouds in the foreground in this region redden the light from NGC 7142, making astronomical exploration of the cluster difficult. These bright young stars are located in a rosebud-shaped (and pink) nebula known as NGC 7129.
