The unprecedented sensitivity of the Cosmic Origins Spectrograph in the far-ultraviolet was used to determine the carbon-monoxide production rate for four recent comets: Hartley 2, Garradd, ISON, and Lovejoy.

Simulations show that while cold stellar disks around classical bulges rapidly form spiral structure and bars, galaxy models with compact classical bulges are able to prevent bar formation for at least 4 Gyr.

New simulations and modeling show that distant ultraviolet-bright galaxies located in overdensities have >2x higher transmission through the z ~ 7 intergalactic medium than typical field galaxies.

Winds driven by active galactic nuclei can only account for <30% of the observed extragalactic gamma-ray background; for small neutrino spectral indices, such winds may still account for the IceCube neutrino flux.

The possibility is explored of systematically measuring microlensing parallax using a telescope based on the Moon’s surface or other space-based observing platform (like the upcoming WFIRST space telescope).
