Rosetta Mission Comes to an End.
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.
Astronomers Capture Best View Ever of Disintegrating Comet
Astronomers have captured the sharpest, most detailed observations of a comet breaking apart 67 million miles from Earth, using NASA's Hubble Space Telescope.
Rosetta's Comet Offered Brief and Powerful Summer Fireworks
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.
Rosetta's Descent Towards Active Pits on Comet 67P
Squeezing out unique scientific observations until the very end, Rosetta's thrilling mission will culminate with a descent on 30 September towards a region of active pits on the comet's 'head'.
Philae Lander Found on Comet 67P
Less than a month before the end of the mission, Rosetta's high-resolution camera has revealed the Philae lander wedged into a dark crack on Comet 67P/Churyumov-Gerasimenko.
Rosetta Captures Comet Outburst
In unprecedented observations made earlier this year, Rosetta unexpectedly captured a dramatic comet outburst that may have been triggered by a landslide.
How Comets Are Born
Understanding how and when objects like Comet 67P/Churyumov-Gerasimenko took shape is of utmost importance in determining how exactly they can be used to interpret the formation and early evolution of our Solar System.
Cliffs on Comet 67P/Churyumov-Gerasimenko
This striking view of Comet 67P/ChuryumovGerasimenko reveals portions of both comet lobes, with dramatic shadows on the 'neck' region between them.
Plans To Crash Land Rosetta On Comet 67P Proceed
Rosetta is set to complete its mission in a controlled descent to the surface of its comet on 30 September.
Hubble Gets Close Look at Comet 252P/LINEAR
This sequence of images taken by NASA's Hubble Space Telescope shows Comet 252P/LINEAR as it passed by Earth. The visit was one of the closest encounters between a comet and our planet.
X-Ray Views Of Comets
Recently, astronomers announced the results of a study using data collected with NASA's Chandra X-ray Observatory of two comets -- C/2012 S1 (also known as "Comet ISON") and C/2011 S4 ("Comet PanSTARRS").
Rosetta's Comet Is Changing Color
Rosetta's comet has been seen changing color and brightness in front of the ESA orbiter's eyes, as the Sun's heat strips away the older surface to reveal fresher material.
Dark Object Observed While Making Close Flyby of Earth
Comet Pan-STARRS made a close flyby of the Earth at a distance of 3.6 million kilometers (2.2 million miles) on March 22.
Philae Comet Lander Faces Eternal Hibernation
Silent since its last call to mothership Rosetta seven months ago, the Philae lander is facing conditions on Comet 67P/ChuryumovGerasimenko from which it is unlikely to recover.
Afternoon View On A Comet
This beautiful landscape feels within arm's reach in this stunning view across the Imhotep region on Comet 67P/ChuryumovGerasimenko.
Exposed Ice on Rosetta's Comet Confirmed as Water
Observations made shortly after Rosetta's arrival at its target comet in 2014 have provided definitive confirmation of the presence of water ice.
Philae Lander: One Year On A Comet
One year since Philae made its historic landing on a comet, mission teams remain hopeful for renewed contact with the lander
