Space Weathering Provides a Lower Limit on the Age of Saturn’s Rings Open
Cassini observations of the micrometeoroid bombardment flux, ring mass and fractional pollution constrain the origin and history of Saturn’s rings. In the simplest model, the age of the rings can be estimated by assuming the rings ar…

The Enigmatic Abundance of Atomic Hydrogen in Saturn’s Upper Atmosphere Open
A planet’s Ly α emission is sensitive to its thermospheric structure. Here we report joint Hubble Space Telescope and Cassini cross-calibration observations of the Saturn Ly α emission made 2 weeks before the Cassini grand finale. To inves…

The Bolocam Galactic Plane Survey. III. Characterizing Physical Properties Of Massive Star-Forming Regions In The Gemini Ob1 Molecular Cloud Open
We present the 1.1 mm Bolocam Galactic Plane Survey (BGPS) observations of the Gemini OB1 molecular cloud complex, and targeted NH3 observations of the BGPS sources. When paired with molecular spectroscopy of a dense gas tracer, millimeter…
