Why do so many comets have a two-lobed, "rubber ducky" shape? It's the result of gentle collisions and mergers, new simulations reveal.
Learn more about the European Space Agency's Rosetta spacecraft that arrived at Comet 67P/Churyumov–Gerasimenko on Aug. 6, 2014.
After a 7-month hiatus, the revived European comet lander is nearly ready to resume work, expanding on our scientific understanding of the solar system.
Electrons from the surface of a comet, not photons from the sun, are responsible for the breakup of water and carbon dioxide molecules, according to new data from the Rosetta mission.
A deluge of new photos by the Rosetta spacecraft shows the haunting alien landscape on the surface of a comet. The images were captured during Rosetta's closest flyby of the space rock.
Living on comets requires great care — the gravity is so weak that you could easily jump off the frozen bodies and into space.
As the European Rosetta spacecraft continues to explore Comet 67P/Churyumov-Gerasimenko as it gradually gets closer to the sun, it's having to deal with some very inclement orbital weather.
The first spacecraft to make a soft-landing on a comet is still quiet on the dusty cosmic body, despite being hailed by another probe orbiting the lander.
The European Space Agency's Rosetta spacecraft took the picture during a close flyby of Comet 67P/Churyumov-Gerasimenko on Feb. 14, when the sun, spacecraft and comet were all neatly aligned.
Europe's Rosetta spacecraft recently beamed back an amazing photo of its comet taken during a risky, close flyby of the dusty cosmic body.
A European spacecraft orbiting a comet continues to beam incredible photos of the icy, dusty cosmic body back to Earth.
The surface of a comet flying through deep space is pockmarked with weird features that are keeping curious scientists working with Europe's Rosetta comet mission busy.
