re: Megascopes
I'll have to look up the details when I get home, but the SciAm article indicated that one of the new scopes could obtain an image of a star (name to be remembered) of 3000 pixels. Not exactly huge, but that would be around 50-60 pixels across - a Jupiter-sized planet might be 5-6 pixels across. Won't be able to read license plates on the exoplanet, but extended observations might give a bit of detail.
