Rosetta: OSIRIS detects hints of ice in the comet's neck

The Hapi region on the neck of Rosetta's comet 67P/Churyumov-Gerasimenko reflects red light less effectively than most other regions on the comet. It thus appears slightly blueish. The Hapi region is located between the comet's two lobes and has in the past months proven to be particularly active and the source of spectacular jets of dust and gas.

The Philae lander has detected organic molecules on the surface of its comet, scientists have confirmed.
The compounds were picked up by a German-built instrument designed to "sniff" the comet's thin atmosphere.

Name Rosetta mission's landing site

ESA and its Rosetta mission partners are inviting you to suggest a name for the site where lander Philae will touch down on Comet 67P/Churyumov-Gerasimenko on 12 November.
As the location of the first soft landing of a human-made object on a comet, the site, currently identified as Site J, deserves a meaningful and memorable name that captures the significance of the occasion.

Europe's space agency (Esa) has finally released a proper model for the shape of Comet 67P/Churyumov-Gerasimenko.
The model provides some further details on the comet's size, and also allows enthusiasts to print their own 3D version of the duck-shaped object.

Scientists have found that the surface of comet 67P/Churyumov-Gerasimenko -- the target of study for the European Space Agency's Rosetta mission -- can be divided into several regions, each characterized by different classes of features. High-resolution images of the comet reveal a unique, multifaceted world.

The comet being followed by Europe's Rosetta spacecraft has a mass of roughly 10 billion tonnes.
The number has been calculated by monitoring the gravitational tug the 4km-wide "ice mountain" exerts on the probe.
Ten billion tonnes sounds a lot, but it means Comet 67P/Churyumov-Gerasimenko has quite a low bulk density, something in the region of 300kg per cubic metre.
