Scientific paper

The Orion Nebula is the nearest region of star formation that includes massive stars and is considered the prototype of the type of object where ordinary stars are formed. Hubble Space Telescope (HST) observations have revealed the presence of protoplanetary disks around a large fraction of the low mass stars there, which are characteristically less than one million years old. We also have found numerous examples of the outflows that seem to be a necessary ingredient in the processes that allow stars to form. The extended period of HST observations has allowed us to see changes in the nebula as the young stars' hypersonic jets cause shocks in the ambient nebular gas. Our observations have raised basic questions about whether protoplanetary disks survive long enough to allow planet formation, or if these disks are too quickly destroyed by the intense radiation field of the youngest and most massive stars.
