The weird "neck" between the lobes of Comet 67P/Churyumov-Gerasimenko spotted by the Rosetta spacecraft formed in part because the comet had a brittle interior, a new study shows.
Learn more about the European Space Agency's Rosetta spacecraft that arrived at Comet 67P/Churyumov–Gerasimenko on Aug. 6, 2014.
If you regard comets as big old dirty snowballs, boringly uniform and featureless, this photo will set you straight.
Nearly 100,000 high-resolution images of a comet, two asteroids, Earth and Mars are now all available to the public online.
More samples of comets are urgently needed to better understand the early history of the solar system, say researchers analyzing comet dust brought back to Earth by NASA’s Stardust mission in 2006.
A Twitter user managed to turn 25 minutes worth of images from the ESA's comet lander into a dramatic short film.
The finding shows that oxygen can be generated in space without the need for life, and could influence how researchers search for signs of life on exoplanets.
Rosetta was a spacecraft launched by the European Space Agency with a 10-year mission to rendezvous with a comet.
Comet 67P/Churyumov–Gerasimenko is a small body visited by the Rosetta spacecraft in the first mission to land on a comet.
Material from the sun may have caused Comet 67P/Churyumov-Gerasimenko to flare up nearly 100 times brighter than average in some parts of the visual spectrum, new research reports.
Comet outbursts are likely caused by landslides rather than pressure-based eruptions from the icy bodies' interiors, a new study suggests.
Today (Sept. 30) marks the end of operations for the European Space Agency's (ESA) historic Rosetta mission, and the mood felt almost funereal as the postlanding celebration began.
The Rosetta probe drifted down to the surface of Comet 67P today (Sept. 30) and ended its 12-year mission.
The Rosetta spacecraft will crash land into Comet 67P after more than a decade in space, concluding one of the greatest unmanned space missions.
At around 6:40 a.m. EDT (1040 GMT) today (Sept. 30), Rosetta is scheduled to crash-land intentionally on Comet 67P/Churyumov-Gerasimenko, ending the European spacecraft's epic 12-year mission.
