Wow, in terms of angle, how far are these planets separated from the star?
I always thought we would never be able to image something like that. The distances would be too small and the contrast too large to figure something at the resolution we can get on earth. I'll need to read up on how this was done.

    TL;DR - Two inside (16, 26AU) and two outside (43, 69AU) Pluto's orbit (39AU). They are all estimated to be a bit bigger than Jupiter.
