The European Southern Observatory (ESO) has been able to capture telescopic images at visible wavelengths from the ground that are sharper than those from the NASA/ESA Hubble Space Telescope. The ground-based Very Large Telescope (VLT) has used an adaptive optics mode called laser tomography to capture images of distant objects in the solar system. The laser tomagraphy compensates for atmospheric turbulence resulting in more detail than anything prior. It works by stimulating sodium ions in the upper atmosphere using two pairs of lasers to calculate the turbulence and adjusting a deformable secondary mirror thousands of times per second in response.

The Large Binocular Telescope announced 3x sharper than Hubble [www.mpg.de] imaging in 2010 with 10x sharper seemingly just around the corner. Where are the resulting astronomy papers? [stsci.edu]

Maybe sharp is still shit for ground telescopes. One of Hubble's major advantages is its infrared capability. That's what allows it to observe highly redshifted objects.
