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.
Where is Philae? When will Philae wake up? These are the two most popular questions currently being asked of the mission especially on our social media channels.
As the Rosetta spacecraft orbits comet 67P/Churyumov-Gerasimenko, an international team of scientists have discovered that the comet's atmosphere, or coma, is much less homogenous than expected and comet outgassing varies significantly over time
Rosetta is revealing its host comet as having a remarkable array of surface features and with many processes contributing to its activity, painting a complex picture of its evolution.
A 3D image shows what it would look like to fly over the surface of comet 67P/Churyumov-Gerasimenko.
These incredible images show the breathtaking journey of Rosetta's Philae lander as it approached and then rebounded from its first touchdown on Comet 67P/Churyumov-Gerasimenko on 12 November 2014.
With its batteries depleted and not enough sunlight available to recharge, Philae has fallen into 'idle mode' -- a possibly long silence. In this mode, all instruments and most systems on board are shut down.
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.
The image shows comet 67P/CG acquired by the ROLIS instrument on the Philae lander during descent on Nov 12, 2014 14:38:41 UT from a distance of approximately 3 km from the surface.
ESA's Rosetta mission has soft-landed its Philae probe on a comet, the first time in history that such an extraordinary feat has been achieved.
The Agilkia landing site is seen on this image of Comet 67P/Churyumov-Gerasimenko, taken with Rosetta's navigation camera on 6 November, just days before its lander Philae makes its historic descent to the surface.
Rosetta's scientific imaging system OSIRIS has caught a glimpse of the southern side of comet 67P/Churyumov-Gerasimenko.
This video sequence is based on an artist's impression of exocomets orbiting the star Beta Pictoris. Astronomers analysing observations of nearly 500 individual comets made with the HARPS instrument at ESO's La Silla Observatory have discovered two families of exocomets around this nearby young star.
Rosetta's comet 67P/Churyumov-Gerasimenko is beginning to show a clearly visible increase in activity.
These images were taken of comet C/2013 A1 Siding Spring by NASA's Mars Reconnaissance Orbiter on Oct. 19, 2014, during the comet's close flyby of Mars and the spacecraft.
