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: 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.

TL;DR: It is reported that pits on comet 67P/Churyumov–Gerasimenko are active, and probably created by a sinkhole process, possibly accompanied by outbursts, and argued that after formation, pits expand slowly in diameter, owing to sublimation-driven retreat of the walls.

TL;DR: This paper investigated the formation and evolution of comet nuclei and other trans-Neptunian objects (TNOs) in the solar nebula and primordial disk prior to the giant planet orbit instability foreseen by the Nice model.

TL;DR: The notable structural similarities between the two lobes of comet 67P/Churyumov–Gerasimenko indicate that the early-forming cometesimals experienced similar primordial stratified accretion, even though they formed independently.
