It appears that using Kepler it might be possible, amazaingly, to detect moons by the small changes they cause in transit times, and "the hunt is on" already: http://www.cfa.harvard.edu/HEK/about_hek.html http://www.time.com/time/health/article/0,8599,2104376,00.html You have to hand it to these guys, they really are on the case, despite the fact that they have such slender threads of data from which to extrapolate. I'm trying to get my head around how one might distinguish between transit time variations arising from an exomoon system, and those arising from an elliptical planetary orbit in a system slowly revolving in relation to Kepler...
