Optical follow-up of a neutrino alert from IceCube found a spatially-coincident, unusual type IIn supernova — but it exploded 158 days before the neutrino detection, so it wasn’t the neutrinos’ source.

Two recently-discovered methane dwarfs, located in the dark cloud L 1688 of the ρ Oph star-forming region, represent the youngest T dwarfs ever confirmed.

The chances of a planet being exposed to a lethal GRB increases at higher redshifts. Simulations show that at z=1.5 (3), 50% (10%) of galaxies have a low enough rate of GRB exposure for life to survive.

N-body simulations show that the eccentricities of planets that result from protoplanet mergers are much smaller than escape eccentricity due to very efficient collision damping.

A possible optical counterpart to ultra-compact high velocity cloud AGC 198606 has been detected by the ALFALFA survey, supporting the idea that this may be a low-mass dwarf galaxy.
