A new study suggests the comet has two internal reservoirs that make it seem like there's more oxygen than is actually there.

When the European Space Agency’s Rosetta spacecraft discovered abundant molecular oxygen bursting from comet 67P/Churyumov-Gerasimenko (67P) in 2015, it puzzled scientists. They had never seen a ...

New analysis from the European Space Agency’s Rosetta mission to Comet 67P/Churyomov-Gerasimenko finds evidence for primordial molecular oxygen from deep within its nucleus, say researchers.

Almost 5 years after a European Space Agency mission to Comet 67P/Churyumov-Gerasimenko ended, scientists reported new findings about the comet’s chemistry at the American Chemical Society ...

GIF Astronomers have discovered an aurora in an unlikely place: Comet 67P. It’s the first time the phenomenon has been detected around an astronomical object that wasn’t a planet or a satellite. The ...

A study finds features in comet 67P/Churyumov-Gerasimenko that illuminate the mechanical properties of materials that formed the comet, showing how the comet's structure was shaped.

But 67P's close encounter with the Sun didn't just release dust: the tiny icy chunk was also expelled from the comet during perihelion. The orbit of 67P. (ESA/Universe Today) The gif is from images ...

Images sent back by ESA's Rosetta comet probe show that it wasn't only thing orbiting comet 67P/Churyumov-Gerasimenko (67P/C-G). A comparison of images taken four years ago when the comet was ...
