How do the latest Earth-based telescopes compare to the Hubble? I noticed these pictures of Uranus taken by the Keck telescope:

Compared to this photo taken by the Hubble Space Telescope:

Folks are doing some impressive stuff with multiple mirrors and algorithms for removing atmospheric effects. Looks like these are the big guns currently:

Palomar - 5 meter single mirror
BTA - 6 meter, single mirror
VLT - 8.2 meter multi-mirror
Keck - 10 meter multi-mirror

There are some intersting plans for huge new Earth-based telescopes like the Califormina 30-meter telescope, the Euro-50 and the 100-meter OWL (Overwhelming Large Telescope!).

OWL is now planned to be 'only' 30m - 100m was just a bit too overwhelming!
