Predictions for the upcoming Wide Field InfraRed Survey Telescope (WFIRST) mission suggest the survey should detect a total of ~1400 bound exoplanets with mass greater than ~0.1 M_⊕ via microlensing.

Recent IBEX observations are consistent with the heliosphere being shaped by the combined flow and magnetic pressures of the local interstellar medium, and they support a non-spherical heliosphere model.

A vast majority of a sample of 49 supermassive black holes at z ~ 6 are more massive than expected from the local black-hole–halo mass relation, suggesting growth of the black holes precedes that of the halos.

The X-ray data for two gamma-ray bursts are fit with a millisecond-magnetar model and a fireball-shock model; the millisecond-magnetar model is favored for most nuclear equations of state.
