NGC 7129 is a star forming region and reflection nebula in the constellation Cepheus. It is about 3750 light years away. The stars in this nebula are very young and only 200.000 to 3 million years old. These more than 130 young stars are responsible for illuminating the nebula. The red blobs surrounding the nebula are Herbig Haro objects, which are the result of jets of gas streaming away from the young stars in the nebula.
