Only two years until James Webb telescope launches. Should keep us entertained for while.

    Note that Webb is an IR telescope, which is longer wavelength, so the resolution actually is comparable to Hubble.

      Does it offer any advantages to Hubble?

        It's highly complementary. IR astronomy is essentially a different field.
