Even JWST has it's limits. There are some very, very, very, very old galaxies that are so red-shifted, JWST is only able to see them thanks to gravitational lensing amplifying the energy of the light. https://www.space.com/james-webb-space-telescope-distant-galaxies https://www.space.com/james-webb-space-telescope-distant-gal...
- PaulHoule 2y agoWhen it comes to the “oldest stars” there is reason to believe that very early there were very big Population III stars that formed very quickly and burned out fast leaving nothing but black holes and there is hope JWST will see some. In general there are multiple recent observations that things seemed to happen much more quickly in the early universe than we expected so maybe what we think was the first 1 billion years was really the first 10 billion years or there is another big secret to be discovered in cosmology.
