They're not part of a vast, Marvel-style universe, and neither is a classic. So why are the "Avatar" movies so successful?
The JWST was built with the power to observe the red-shifted light from objects in the very early Universe. Once it got going, the telescope practically inundated us with surprising, theory-challenging observations from the Universe's earliest ages. Some ancient galaxies were much larger and fully-formed than thought. So were their supermassive black holes (SMBH).
