Gravitational scattering among planets in a system, combined with a close flyby of another star, may generate a population of “Oort” exoplanets that orbit at wide distances of 100 to 5,000 AU.

This review summarizes the origins and evolution of the burgeoning field of exoplanet climatology, work to identify those planets most capable of supporting life, and offers a glimpse into future directions of the field.

New observations suggest at least some Green Peas — compact, highly star-forming dwarf galaxies — produce copious amounts of highly energetic photons, larger than detected in other star-forming galaxies.

The Nautilus concept is based on an array of inflatable spacecraft carrying very large diameter (8.5 m), very low weight lenses, enabling the characterization of 1,000 transiting exo-Earth candidates.

Models of angular momentum transport in massive evolving stars suggest that black holes born from single stars rotate very slowly (a < 0.01) regardless of the initial rotation rate.

A systematic analysis of all high-energy neutrino events satisfying the IceCube realtime trigger criteria found a gamma-ray blazar, GB6 J1040+0617, in spatial coincidence with a neutrino from this sample.
