This review presents our understanding of cometary dust at the end of 2017. For decades,
insight about the dust ejected by nuclei of comets had stemmed from remote observations …

Extensive evidence of landform-scale martian geomorphic changes has been acquired in
the last decade, and the number and range of examples of surface activity have increased …

Images from the OSIRIS scientific imaging system onboard Rosetta show that the nucleus of
67P/Churyumov-Gerasimenko consists of two lobes connected by a short neck. The nucleus …

Abstract The Rosetta spacecraft reached Comet 67P/Churyumov-Gerasimenko (hereafter
67P/CG) in August 2014 at an heliocentric distance of 3.6 au and was then put in orbit …

The Philae lander, part of the Rosetta mission to investigate comet 67P/Churyumov-
Gerasimenko, was delivered to the cometary surface in November 2014. Here we report the …

Comets contain the best-preserved material from the beginning of our planetary system.
Their nuclei and comae composition reveal clues about physical and chemical conditions …

The processes that led to the formation of the planetary bodies in the Solar system are still
not fully understood. Using the results obtained with the comprehensive suite of instruments …

The ESA Rosetta spacecraft followed comet 67P at a close distance for more than 2 yr. In
addition, it deployed the lander Philae on to the surface of the comet. The (surface) …

We analyzed more than 200 OSIRIS NAC images with a pixel scale of 0.9− 2.4 m/pixel of
comet 67P/Churyumov-Gerasimenko (67P) that have been acquired from onboard the …

Context. The Rosetta mission of the European Space Agency has been orbiting the comet
67P/Churyumov-Gerasimenko (67P) since August 2014 and is now in its escort phase. A …
