Cataclysmic variables are binary star systems where one of the stars—a white dwarf—devours its main sequence partner over time. Kepler proves yet again that it can find a lot more than just exoplanets by identifying a cataclysmic variable with a period of less than an hour.
Planetary radius is found to depend strongly on planet composition. The observed planet radius distribution can be recast as a composition distribution, with implications for the way planets form.
Our Solar System is pretty straightforward. Roughly speaking, all the planets orbit in the same plane, most spin on their axes in the same direction in that plane, and even the Sun rotates in a manner consistent with all this. The small, rocky planets are closer to the Sun, and the big, gaseous planets are farther from the Sun. Simple. Now that we are finding planets orbiting other stars, many are turning out to be multiplanet systems like our own Solar System.

Dust traps may be the key to forming Kepler-16b and other circumbinary planets.
NASA is looking for a new mission for the damaged Kepler space telescope. Here are some ideas.
A study of Kepler data reveals a correlation between brightness fluctuations and surface gravity of stars.
The recent discovery of two planets in an open star cluster implies that planet formation can survive the harsh environments of a dense stellar cluster.
