Numerical simulations of resonant planet-planet interactions show that close-proximity pairs of planets that lie in their host’s habitable zone can be conducive to life in the system.

The best model of Kepler M-dwarf planet hosts predicts that roughly half of these hosts contain ~7 coplanar planets. The other half contain single planets, or multiple planets with large mutual inclinations.

Hubble measurements show that the Smith Cloud is metal-enriched, suggesting it represents recycled Galactic material rather than a dwarf galaxy remnant or accreting intergalactic gas.
Jason Galyardt and Robin L. Shelton 2016 ApJ 816 L18
If the Smith high velocity cloud has a dark-matter minihalo, simulations suggest the cloud’s gas was accreted in a collision with the Galactic disk. If it’s dark matter free, then this is the cloud’s first approach.

New data and analysis finds an orbital decay rate for the short-period exoplanet WASP-43b of ~0.029 s/yr, an order of magnitude lower than previously reported rates.

No significant source of transient neutrino emission was found in the low-energy (30–300 GeV) muon-neutrino sample collected by IceCube, providing some upper limits on their production.
