    Obvious, JWT delivers more detailed images than the Huble, but is it the near IR has to do
    with it or simply the size of the mirrors, 2m vs. 6.5 m?

    The bigger mirrors increase the JWST's resolultion.
    The longer wavelength of the light *decreases* it.
    However, the use of infrared helps by letting the telescope see through interstellar gas and dust.
