Subaru and HiCIAO observations of the transitional disk around solar-like star GM Aur resolves a large inner cavity with radius 18 AU and suggests the possible presence of a 3–4 Jupiter-mass planet at ~20 AU.

The first circumbinary microlensing event, OGLE-2007-BLG-349, reveals a planet orbiting two M dwarf stars that total ~0.7 solar masses. This is the lowest-mass circumbinary planet system known.

Observed galaxy stellar mass functions up to z~8 are used to estimate the evolution of the number density of galaxies in the universe. Results suggest a total of 2 trillion galaxies exist in the universe up to z~8.

A spread is found in the iron abundance distribution in the globular cluster M22, supporting a model wherein M22 was formed by the merger of two globular clusters and then later accreted onto our galaxy.

The star with unusual dimming events is confirmed to have monotonically faded over 4 years of Kepler observations. Nearby stars did not show the same effect, ruling out obstruction in the ISM.
