Compared to what? They surely blow away my astrophotos! :P Things like looking for IR spectra of water vapor in the atmosphere of planets outside of our solar system we can't even do from earth, since our own atmosphere is not transparent at those wavelengths due to the water in it. (ditto for oxygen). A thing they mentioned in the presentation today but mostly only in passing, was that images like that deep field image were captured with only something like a dozen hours of data collection and had better resolution and much better SNR and many more far redshift objects visible at all than an image of the same scene that took Hubble weeks of data collection to make.
