NGC 7129 is a reflection nebula located about 3000 light years away in Cepheus. The nebula is illuminated by a young cluster of stars, estimated to be only 1 million years old. Of particular interest (to me, at least) are several bright red structures, believed to be Herbig-Haro objects. They hide newly formed or still-forming stars that are not yet directly visible.
