Comets TOP STORY
A new study has revealed similarities and relationships between certain types of chemicals found on 30 different comets, which vary widely in their overall composition compared to one another.

ESA's historic Rosetta mission has concluded as planned, with the controlled impact onto the comet it had been investigating for more than two years
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 have captured the sharpest, most detailed observations of a comet breaking apart 67 million miles from Earth, using NASA's Hubble Space Telescope.
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.
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'.
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.
In unprecedented observations made earlier this year, Rosetta unexpectedly captured a dramatic comet outburst that may have been triggered by a landslide.
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.
This striking view of Comet 67P/ChuryumovGerasimenko reveals portions of both comet lobes, with dramatic shadows on the 'neck' region between them.
Rosetta is set to complete its mission in a controlled descent to the surface of its comet on 30 September.
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.
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 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.
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.
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.
This beautiful landscape feels within arm's reach in this stunning view across the Imhotep region on Comet 67P/ChuryumovGerasimenko.
Observations made shortly after Rosetta's arrival at its target comet in 2014 have provided definitive confirmation of the presence of water ice.
