New class of metal-organic compounds found in meteorites

A paper in PNAS last week announced the discovery of a unique class of metal-organic compounds. They were found in meteorites that experienced severe impacts in the past.

Stellar occultations of planetary rings: from Palomar to Cassini

, 12:00 PM - 1:00 PM
Chance observations of stars as they pass behind planets have provided some of our most valuable data on the structure of planetary ring systems, beginning with the discovery of the uranian rings with the Kuiper Airborne Observatory in 1977.
Ceres Observations

Observations of Ceres indicate that asteroids might be camouflaged

MOUNTAIN VIEW – The appearance of small bodies in the outer solar system could be deceiving. Asteroids and dwarf planets may be camouflaged with an outer layer of material that actually comes from somewhere else.
