How much details we can see if based on the wavelength of light and the diameter of the telescope. And if you worked it out, the telescope diameter would have to be enormous. https://calculator.academy/diffraction-limit-calculator/#f1p1|f2p0 https://calculator.academy/diffraction-limit-calculator/#f1p... However gravity can bend light so there is some thought of using the sun as a lens. However the observation would have to be pretty far away from our sun so its just wishful thinking in our lifetime. https://www.freethink.com/space/gravity-telescope https://www.freethink.com/space/gravity-telescope For now the best we will have to see a dot on image via coronagraphy and maybe understand more about the exoplanet through spectroscopy.
