Chandra observations of the deeply embedded Serpens South star-forming region revealed a total of 152 X-ray sources, many of which are confirmed to be young stars that formed in a dense filament.

White dwarfs with effective temperatures above ~10,000 K require accretion rates several orders of magnitude larger than previously inferred, if one uses models that account for thermohaline mixing.

The observed configuration of the TRAPPIST-1 system is unlikely if a Jovian-mass planet inclined by ≥3° to the transiting planet exists within 0.53 AU, constraining a putative planet beyond the transiting seven planets.

A publicly available catalog is presented of 196 solar filament oscillations from the Global Oscillation Network Group Hα network data during several months near the maximum of solar cycle 24.

New molecular data from the Orion Nebula Cluster suggest that that the two clouds collided with each other < 0.1 Myr ago, triggeing the formation of the high-mass stars observed.

New Hubble Space Telescope observations of the unique, dust-ejecting inner-belt asteroid 311P/PANSTARRS suggest that this source may actually be a close, eclipsing binary.
