Rosetta finds comet connection to Earth's atmosphere
The challenging detection, by ESA's Rosetta mission, of several isotopes of the noble gas xenon at Comet 67P/Churyumov-Gerasimenko has established the first quantitative link between comets and the atmosphere of Earth.
Rosetta's ongoing legacy
Rosetta’s operational mission ended in September 2016, but for the scientists and instrument teams the mission is far from over. Scientists have only scratched the surface analysing the amount of data produced by the mission. As this information is scrutinised, new discoveries are made, including a surprise final extra image taken by the OSIRIS camera during the spacecraft’s controlled descent onto the comet.
The 67P/Churyumov-Gerasimenko observation campaign in support of the Rosetta mission
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67P/Churyumov-Gerasimenko from before Rosetta's arrival until nearly the end of mission in September 2016.
Comet 67P Found to Be Producing Its Own Oxygen in Deep Space
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.
The Many Faces of Rosetta’s Comet 67P
A 100 foot-wide (30 meter), 28-million-pound (12.8-million-kilogram) boulder, was found to have moved 460 feet (140 meters) on comet 67P/Churyumov–Gerasimenko in the lead up to perihelion in August 2015, when the comet’s activity was at its highest...
