- The origin of the structure in the Universe is one of the most fundamental problems in astrophysics.
- This is likely to be a field where significant progress is make in the next 25 years as new telescopes now in the planning stages will prove powerful tools ? Observe stars in process of formation ? Learn about control of the formation of stars and ISM ? Discover seeds of structure we now observe ? Observe raw materials of structure at early epochs ? Observer first Galaxies
