Comet landslide recorded for first time by Rosetta astronomers

Images reveal dramatic collapse of a 100 metre-long cliff on comet 67P/Churyumov-Gerasimenko

A landslide on a comet has been documented by astronomers for the first time in images that reveal the dramatic collapse of a 100 metre-long cliff.

The observations by the Rosetta spacecraft of the comet 67P/Churyumov-Gerasimenko, provide before and after snapshots, which show how the dusty avalanche has left a large patch of pristine ice from the comet's interior exposed.
