Photographing Pluto up-close for the first time has been (regrettably) de-valued by the illustrations we have seen in books for decades. Seeing the same thing you've already seen hasn't got much inspiration value as there's no immediate wow unless you're already "into" the subject, in which case you probably don't need to be inspired. Beagle 2 and so on were vastly more inspirational and as such were vastly more widely covered.
Pentaquarks are a subject that for most people is just beyond unimaginably difficult to comprehend, let alone be inspired by. Those that are gifted enough to understand what it actually means at an age young enough to be filtered into the educational streams will probably already be there.
We need much more grounded inspirational subjects to inspire people into STEM education/vocations. I'd say SpaceX's re-usable launch vehicles are pretty inspirational and vastly more accessible to young and eager minds than subatomic particle physics. The challenge of the engineering is visible and obvious even if the maths, engineering and physics of what they are doing might be just as complex.
