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.
