Rosetta’s Comet Sparkles with Ice, Blows Dust From Sinkholes

Example of a cluster of bright spots on Comet 67P/Churyumov-Gerasimenko found in the Khepry region. The bright patches are thought to be exposures of water-ice. Credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

Comet 67P/C-G may be tiny at just 2.5 miles (4 km) across, but its diverse landscapes and the processes that shape astound. To say that nature packs a lot into small packages is an understatement.

In newly-released images taken by Rosetta’s high-resolution OSIRIS science camera, the comet almost seems alive. Sunlight glints off icy boulders and pancaking sinkholes blast geysers of dust into the surrounding coma. (…)
