Rosetta’s comet 67P is much younger than previously thought
Based on computer simulations, astrophysicists at the University of Bern conclude that comet 67P/Churyumov–Gerasimenko did not obtain its duck-like form during the formation of our solar system 4.5 billion years ago. Although it does contain primordial material, they are able to show that the comet in its present form is hardly more than a billion years old.
