Rosetta's target "Chury" and other comets observed by space missions show common evidence of layered structures and bi-lobed shapes. With 3D computer simulations Martin Jutzi of PlanetS at the University of Bern was able to reconstruct the formation of these features as a result of gentle collisions and mergers. The study has now been published online in the journal Science Express.
