Scientists analyzing the treasure trove of images taken by ESA’s Rosetta mission have turned up more evidence for curious bouncing boulders and dramatic cliff collapses.

Rosetta operated at Comet 67P/Churyumov-Gerasimenko between August 2014 and September 2016, collecting data on the comet’s dust, gas and plasma environment, its surface characteristics and its interior structure.

As part of the analysis of some 76 000  captured with its OSIRIS camera, scientists have been looking for surface changes. In particular, they are interested in comparing the period of the comet’s  to the Sun—known as perihelion—with that after this most active phase,
