Why aren't ground-based observatories using adaptive optics for visible wavelengths (circa 2016)?
Adaptive Optics (AO) techniques allow ground based observatories to dramatically improve resolution by actively compensating for the effects of Astronomical Seeing.
The atmospheric effects are quite ...

How did VLT's adaptive optics obtain this resolution for Neptune? Is it really working in visible wavelengths?
This image of Neptune taken with the VLT is really impressive. The resolution is achieved by recent improvements in the adaptive optics.

What (if any) capabilities of Hubble are unique and irreplaceable? What can it do that can't be done by any other ground or space-based telescope?
It's impossible to summarize in an SE post the depth and breadth of the contributions to science made using the Hubble Space Telescope.
Above the atmosphere it has
access to an extremely dark and ...

What can be learned from low frequency radio astronomy available outside of Earth's ionosphere?
As discussions and answers to How large does refraction become in radioastronomy? point out, it is difficult to do radio astronomy much below 30 MHz (or 10 MHz depending on how aggressive you are in ...
