Ground-based stellar occultation measurements of Pluto’s atmosphere two weeks before the New Horizons flyby show that its atmosphere is still expanding, with a 5% pressure increase since 2013.

Three Kepler binaries have known planets in their circumbinary habitable zones. The high-energy radiation levels and plasma environment are examined for these systems.

Capture is mostly retrograde for asteroids near the planetary orbit and prograde for those from farther orbits. Thus Jupiter’s prograde satellites likely originated from inner regions like the main asteroid belt.

New radial velocity and photometric observations of the HD 99492 planetary system reveal that the host star has a 13-year activity cycle, suggesting detections of a 13-year-period outer planet are false.

New measurements of Hydra I’s intermediate age and metallicity suggest its progenitor was a dwarf galaxy that has subsequently lost more than 99.99% of its stellar mass.
