ESA Science & Technology - Comet changes

Showcase of the different types of changes identified in high-resolution images of Comet 67P/Churyumov-Gerasimenko during more than two years of monitoring by ESA's Rosetta spacecraft.

The approximate locations of each feature are marked on the central context images. Dates of when the 'before' and 'after' images were taken are also indicated. Note that the orientation and resolution between image pairs may vary, therefore in each image set arrows point to the location of the changes, for guidance.

Full descriptions and additional images of each feature are provided at the links below:

• Moving boulder
• Scarp retreat
• Collapsing cliff
• Erosion and exhumation
• Texture changes
• Scarp formation
• Ripple evolution
• Fracture growth
