  Ranked near the top of the long list of exciting discoveries made with NASA's
Kepler photometer is the detection of transiting circumbinary planets. In just
over a year the number of such planets went from zero to seven, including a
multi-planet system with one of the planets in the habitable zone (Kepler-47).
We are quickly learning to better detect and characterize these planets,
including the recognition of their transit timing and duration variation
"smoking gun" signature. Even with only a handful of such planets, some
exciting trends are emerging.
