This view of NGC 7129 shows the many vivid red outflows of gas called Herbig Haro (HH) objects
. The HH objects tend to congregate in the northeast and southwest ridges of the nebula. In the northeast are HH105 and GGD34 and GGD35. In the southwest are GGD32 and the most prominent HH object in the region - the crescent shaped HH103
located in the lower right outer region of the nebula.
Notice the cavitation (36 light years across) of the nebula caused by two young B-Type stars deep within the core emitting intense ultraviolet radiation. These two stars are less than 1 million years old and have been clearing out the center of the nebula for about 100,000 years
