A telescope array that can use our sun's gravitational lens would enable us to resolve the surfaces of extrasolar planets. We could resolve surface features as small as 10 km across at a distance of 100 light years.
JPL is actively investigating this. It's incredibly promising.
Yeah, though I have some doubts as to how certain it is that it would really produce results that impressive. Maybe this is quite speculative. There could be tiny inaccuracies which reduce the image quality substantially.
