- ceejayoz 2y agoWhich aspect of the answer do you want? You can write a textbook on such a broad question; how we determine the mass of a galaxy, its composition, its distance, etc. JWST is seeing brand new things; globular clusters are so well documented as to be part of the original Messier catalog that predates the United States.
- blueflow 2y agoThe answer is not rocket science. JWST saw something, scientists made an interpretation, there should be an explanation "why" somewhere. And you won't need to write a textbook on that because you can cite prior work.
- ceejayoz 2y agoThere is no solid/proven explanation right now. Only hypotheses to be tested. It’s a new phenomenon they’re working to understand.
