Comet 67P/C-G is a dusty object. As it neared its closest approach to the Sun in late July and August 2015, instruments on Rosetta recorded a huge amount of dust enshrouding the comet.

Rosetta's Comet Sculpted by Stress

Feeling stressed? You're not alone. ESA's Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov-Gerasimenko has been a key process in sculpting the comet's surface and interior following its formation.

The Rosetta mission came to an end today with the orbiter purposefully "crash" landing (softly) on the Comet 67P/Churyumov-Gerasimenko just as the Philae lander had done previously.

Brief but powerful outbursts seen from Comet 67P/Churyumov-Gerasimenko during its most active period last year have been traced back to their origins on the surface.

On 30 July, the first papers covering the scientific results obtained by Philae on the surface of Comet 67P/Churyumov-Gerasimenko were published in Science magazine.

On 13 August, Comet 67P/Churyumov-Gerasimenko reaches its closest point to the Sun (perihelion) and the Rosetta orbiter will be there to see exactly what happens.

The Rosetta orbiter is continuing its science until the end of the extended Rosetta mission in September 2016. The lander's future is less certain. This film covers some of what we've learnt from Philae about comet 67P/Churyumov-Gerasimenko so far.

This single frame Rosetta navigation camera image was taken from a distance of 124 km from the centre of Comet 67P/Churyumov-Gerasimenko on 6 February 2015.

This four-image mosaic comprises images taken from a distance of 28.0 km from the centre of Comet 67P/Churyumov-Gerasimenko on 31 January.

Rosetta fuels debate on origin of Earth's oceansESA's Rosetta spacecraft has found the water vapour from its target comet to be significantly different to that found on Earth. The discovery fuels the debate on the origin of our planet's oceans.

This four-image montage comprises images taken on 26 November from a distance of 30.1 km from the centre of 67P/Churyumov-Gerasimenko. The image resolution is 2.4 m/pixel so each original 1024 x 1024 pixel frame measures about 2.5 km across.

The European Space Agency provided and early morning update on the Rosetta mission discussing primarily the science results. Since the last update yesterday, ESA has decided not to fire the anchor harpoons which were need to secure the Philae lander on the surface on the comet.

Watch today's Rosetta media briefing, held at ESA's Space Operations Centre, Darmstadt, Germany, at 8:00 a.m. EST (1300 GMT). The replay runs about 45 minutes and includes updates from the Rosetta mission operations team, the Philae lander manager and scientists, as well as presentation of initial images and data from the surface of Comet 67P/Churyumov-Gerasimenko.

It was 45 years ago when astronomer Klim Churyumov and Svetlana Gerasimenko, one of his researchers, unwittingly began a new chapter in the history of space exploration.

The four images that make up this montage of comet 67P/Churyumov-Gerasimenko were taken on Sept. 26, 2014 by the European Space Agency's Rosetta spacecraft.

Comet 67P/Churyumov-Gerasimenko is offering mission managers a variety of scientifically useful targets to chose from for the landing site of the Rosetta's small lander Philae. Which location will they select? The announcement is set for Monday, September 15.

Scientists working on images of comet 67P/Churyumov-Gerasimenko have divided the comet's surface into a number of different regions based on their morphology, revealing a unique, multifaceted world.

Rosetta Landing Site Search Narrows

Using detailed information collected by ESA's Rosetta spacecraft during its first two weeks at Comet 67P/Churyumov-Gerasimenko, five locations have been identified as candidate sites to set down the Philae lander in November - the first time a landing on a comet has ever been attempted.

Full-frame NAVCAM image taken on 21 August 2014 from a distance of about 69 km from comet 67P/Churyumov-Gerasimenko.

Rosetta navigation camera image taken on 18 August 2014 at about 84 km from comet 67P/Churyumov-Gerasimenko. The comet nucleus is about 4 km across.
