… and lots of lasers!

Using adaptive optics—the thing where you shoot the sky with ' lasers to produce artificial guide stars to measure atmospheric distortion—, the ESO's imaginatively named "Very Large Telescope" (VLT) can now produce images matching the useful resolution of the venerable Hubble telescope, but from a far less awkward position. The same technology will be applied to the upcoming Extremely Large Telescope (ELT) with its 39 metre primary mirror, compared to the puny 8.2m of the VLT, so that should produce some exquisite shots.
