Comet 67P/Churyumov-Gerasimenko
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.
Activity on Comet 67P/Churyumov-Gerasimenko Increases
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.
Searching for Philae
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.
Rosetta Data Reveals More Surprises About Comet 67P
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
Getting to Know Rosetta's Comet
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.
Rosetta Comet Landing in 'Thud' and 3D
A 3D image shows what it would look like to fly over the surface of comet 67P/Churyumov-Gerasimenko.
Osiris Spots Philae Drifting Across Comet 67P/C
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.
Philae Is Now Sleeping On A Comet
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.
Video and Image: Rosetta Mission Results from Philae 14 November 2014 
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.
Video and Images: Rosetta Mission Philae Lander Media Briefing 13 November 2014
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.
Philae Image of Comet From 3 km
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.
Touchdown! Rosetta's Philae probe lands on comet
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.
Philae Prepares to Land on Comet 67P/Churyumov-Gerasimenko
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 Glimpses the Dark Side of Comet 67P/C-G
Rosetta's scientific imaging system OSIRIS has caught a glimpse of the southern side of comet 67P/Churyumov-Gerasimenko.
Artist's Impression of Exocomets Orbiting the Star Beta Pictoris
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.
Dust Streams from Comet 67P/Churyumov-Gerasimenko
Rosetta's comet 67P/Churyumov-Gerasimenko is beginning to show a clearly visible increase in activity.
Mars Reconnaissance Orbiter Image Shows Comet Nucleus is Small
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.
