But additionally, the space telescope has spotted some Jupiter-sized objects orbiting stars, and these objects are hotter than the [...]

One of these new planets is similar in many ways to Neptune, although its irradiation level is much higher. A second planet is one of the least dense planets ever discovered, and along with the other three, confirms the existence of planets with densities substantially lower than those predicted for gas giant planets. Borucki said Kepler 7b has the density of styrofoam, at .17 grams per cubic centimeter, basically a density of zero.

That is just plain silly. Something's wrong.
