TL;DR: The temperature and density profiles, as determined by the Huygens Atmospheric Structure Instrument (HASI), from an altitude of 1,400 km down to the surface were higher than expected and the extent of atmospheric electricity was also hitherto unknown.

TL;DR: 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, which raises the question of whether the two Lobes represent a contact binary formed 4.5 billion years ago, or a single body where a gap has evolved via mass loss.

TL;DR: In this article, the GIADA (Grain Impact Analyser and Dust Accumulator) experiment on the European Space Agency's Rosetta spacecraft orbiting comet 67P/Churyumov-Gerasimenko was used to detect 35 outflowing grains of mass 10−10 to 10−7 kilograms.

TL;DR: The Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) as discussed by the authors is the scientific camera system onboard the Rosetta spacecraft, which consists of a high resolution Narrow Angle Camera (NAC) and a wide angle Camera (WAC) units accompanied by three electronics boxes.

TL;DR: Images of comet 67P/Churyumov-Gerasimenko acquired by the OSIRIS imaging system onboard the European Space Agency’s Rosetta spacecraft offer some support for subsurface fluidization models and mass loss through the ejection of large chunks of material.
