However, it has planets thought to be in the Goldi-locks zone around one of the stars. Seems like if they can get that kind of resolution at 300ly, they should be able to do infinitely better at 4. Just a thought, I am sure I am missing something.
A comment upthread mentions that one of the biggest obstacles to detecting planets is the huge contrast between the planet and its host star: detecting 10-14 orders of magnitude difference between the luminosity of a star and orbiting planet cannot be made simpler by adding in 2 additional stars.
