Saturn’s moon Atlas exhibits a chaotic orbit whose dynamics are primarily controlled by resonant perturbations from the moon Prometheus. This may be common in satellite evolution around giant planets.

A set of machine-learning tools are shown to be useful for automatically differentiating between stars and galaxies in large survey catalogs, and also for estimating photometric redshifts of galaxies.

Optical observations of V404 Cyg prior to its X-ray outburst suggest this black hole’s disk entered the hot, outburst state before the X-ray outburst. The event may have been triggered by a disk instability.

NIR Hubble observations of Orion molecular clouds reveal that the fraction of stars with 100-1000 AU companions is ~50% higher in the high-stellar-density regions, relative to the low-density regions.

The Fermi Gamma-ray Burst Monitor locates an average of ~2 gamma-ray burst events every 3 days. The catalog of these events, spanning 2008 to 2014, contains 1405 triggers identified as GRBs.

Stability calculations show that planets within the habitable zone of either α Cen A or α Cen B — the binary components of the nearest star system to us — are able to remain in circumstellar orbit.
