There are limits to angular resolution, and one way to get around them is by combining data from distant detectors.
From a recent thread, current detectors can image objects the size of Mercury's orbit around the sun, at the distance of Sagittarius A* - were these scaled to the size of an adult human eye, it would be like seeing a small apartment building in London, while standing in LA.
