Rosetta Provides Evidence for Daily Water-Ice Cycle on 67P/Churyumov-Gerasimenko

Researchers using the Visible, InfraRed and Thermal Imaging Spectrometer aboard ESA’s Rosetta spacecraft have identified a region on the surface of 67P/Churyumov-Gerasimenko where water ice appears and disappears in sync with its rotation period. The scientists report on this discovery in the current issue of the journal Nature. Comets are impressive phenomena in the night [...] —> Read More
