The cover is a photograph of Super-Kamiokande, the detector at the far end of our experiment where we look to see what has happened to our neutrinos. It does look amazing, so always gets the attention, but equally important is the ND280 "near detector":
Anyway, please do have a look: there were plenty of fantastic questions that we answered, so I think it should be useful in learning about the sorts of things we do on our experiment!
