I thought Earth bound telescopes had problems with their resolution due to the atmosphere

They must be using Adaptive Optics, it can compensate for atmospheric disturbances and produce images almost as good as space-based telescopes.
I don't think that technology was available when Hubble was launched.

‘Adaptive Optics’ to overcome atmospheric effects are not necessarily a blessing. The process of ‘adapting’ introduces uncertainties and biases, depending upon the methodologies and algorithms used, that can create endless opportunities for questioning the quality and accuracy of the resulting images. Think of it as an on-going filtration and manipulation of the ‘image data’ ...
