+1 see also Have interference effects (in space) ever been observed by a single instrument, as opposed to interferometry? and just for fun Are astronomers waiting to see something in an image from a gravitational lens that they've already seen in an adjacent image? and perhaps Has a gravitational microlensing event ever been predicted? If so, has it been observed?
