Rosetta's OSIRIS camera team has launched a new website to showcase their recent images of Comet 67P/Churyumov-Gerasimenko.

One year since Philae made its historic landing on a comet, mission teams remain hopeful for renewed contact with the lander, while also looking ahead to next year's grand finale: making a controlled impact of the Rosetta orbiter on the comet.

ESA's Rosetta spacecraft has made the first in situ detection of oxygen molecules outgassing from a comet, a surprising observation that suggests they were incorporated into the comet during its formation.

Two comets collided at low speed in the early Solar System to give rise to the distinctive 'rubber duck' shape of Comet 67P/Churyumov-Gerasimenko, say Rosetta scientists.

ESA's Rosetta spacecraft has provided evidence for a daily water-ice cycle on and near the surface of comets.

Extreme thermal stresses experienced by a comet as it orbits around the Sun could explain the extensive fracturing thought to drive its long-term surface erosion, say Rosetta scientists analysing high-resolution images of Comet 67P/Churyumov-Gerasimenko's surface.

ESA's Rosetta today witnessed Comet 67P/Churyumov-Gerasimenko making its closest approach to the Sun. The exact moment of perihelion occurred at 02:03 GMT this morning when the comet came within 186 million km of the Sun.

In the approach to perihelion over the past few weeks, Rosetta has been witnessing growing activity from Comet 67P/Churyumov-Gerasimenko, with one dramatic outburst event proving so powerful that it even pushed away the incoming solar wind.

ESA's Rosetta mission today celebrates one year at Comet 67P/Churyumov-Gerasimenko, with its closest approach to the Sun now just one week away.

Complex molecules that could be key building blocks of life, the daily rise and fall of temperature, and an assessment of the surface properties and internal structure of the comet are just some of the highlights of the first scientific analysis of the data returned by Rosetta's lander Philae last November.

Rosetta is making good progress in one of its key investigations, which concerns the interaction between the comet and the solar wind.

Rosetta's investigations of its comet are continuing as the mission teams count down the last month to perihelion – the closest point to the Sun along the comet's orbit – when the comet's activity is expected to be at its highest.

A number of the dust jets emerging from Rosetta's comet can be traced back to active pits that were likely formed by a sudden collapse of the surface. These 'sinkholes' are providing a glimpse at the chaotic and diverse interior of the comet.

Using the high-resolution science camera on board ESA's Rosetta spacecraft, scientists have identified more than a hundred patches of water ice a few metres in size on the surface of Comet 67P/Churyumov-Gerasimenko.

The adventure continues: ESA today confirmed that its Rosetta mission will be extended until the end of September 2016, at which point the spacecraft will most likely be landed on the surface of Comet 67P/Churyumov-Gerasimenko.

In two papers, accepted for publication in Astronomy & Astrophysics, scientists provide an update on their study of debris around the comet.

In a paper accepted for publication in the journal Astronomy & Astrophysics, the MIRO team present their first map of water vapour in the coma of Comet 67P/Churyumov-Gerasimenko.

The receipt of signals from Rosetta's Philae lander on 13 June after 211 days of hibernation marked the start of intense activity. In coordination with its mission partners, ESA teams are working to juggle Rosetta's flight plan to help with renewed lander science investigations.

Rosetta's lander Philae has woken up after seven months in hibernation on the surface of Comet 67P/Churyumov-Gerasimenko. The signals were received at ESA's European Space Operations Centre in Darmstadt at 22:28 CEST on 13 June. More than 300 data packets have been analysed by the teams at the Lander Control Center at the German Aerospace...

Rosetta's continued close study of Comet 67P/Churyumov–Gerasimenko has revealed an unexpected process at work, causing the rapid breakup of water and carbon dioxide molecules spewing from the comet’s surface.
