Young Stars and Clusters
When we look towards young star forming regions, we see a variety of
interesting objects. In the constellation of Orion, there is a famous
nebula which contains several very young massive stars. And all
around in the nebula, other curious objects are found.
Objects such as T Tauri Stars (solar mass pre-main sequence objects) and
other indicators of youth are found here. What is shown in the close up
images above are pre-planetary disks, called propylids.
