You might have been thinking that Pluto is just too far away for any detail on its surface to be seen. Actually the Hubble Space Telescope's resolution is a good deal sharper than Pluto's diameter, so it can pick out dark and light areas, though it's not quite good enough for the fine detail of craters and cracks, etc. For that, we will have to wait for the New Horizons probe to grab some pictures as it whips past on its way out of the solar system.
