7142 is the open cluster at the upper right. It it estimated to
be 3 billion years old. Despite its very old age, the cluster contains
several blue "stragglers".
7129 is the reflection nebula visible at the lower right of the
frame. It contains approximately 130 young (i.e., 1 million-year-old)
stars. The reddish formations within it are Herbig-Haro objects
- jets formed by stellar winds of newborn stars.
these objects appear very close to each other, NGC 7129 lies 3 thousand
light years away while NGC 7142 is twice that distance.
