is a decrease from the 54 reported in February 2011 only because the Kepler team
is now applying a stricter definition of what constitutes a habitable

zone away from the star, outwards in orbital
distance resulting in longer orbital periods (NASA news release; and Kepler Press Conference slides — in pdf).
