Salinity of Europa's Ocean

New research from NAI's SETI Institute Team published online in Icarus today outlines the empirical range of salt concentrations permitted for Europa's ocean. Solutions within the range imply high, near-saturation salt concentrations and require a Europan ice shell of less than 15 km thick, with a best fit at 4 km ice thickness. The paper examines the implications for subsurface habitability. [source: NAI Newsletter]

Astrobiology Pilot PBS Program Online

Pilot episodes of a new science television series, including one on "Extreme Virology," are available for viewing online. Produced by WIRED SCIENCE, a collaboration between WIRED Magazine and KCET/Los Angeles, these pilots may evolve into a larger PBS science program featuring astrobiology science topics.
