TL;DR: The presence of volatile glycine accompanied by methylamine and ethylamines in the coma of 67P/Churyumov-Gerasimenko measured by the ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) mass spectrometer demonstrates that comets could have played a crucial role in the emergence of life on Earth.

TL;DR: The observations indicate that the O2/H2O ratio is isotropic in the coma and does not change systematically with heliocentric distance, which suggests that primordial O2 was incorporated into the nucleus during the comet’s formation, which is unexpected given the low upper limits from remote sensing observations.
Journal ArticleDOI
Time variability and heterogeneity in the coma of 67P/Churyumov-Gerasimenko

TL;DR: Rosetta Orbiter Spectrometer for Ion and Neutral Analysis onboard the Rosetta spacecraft has measured the coma composition of comet 67P/Churyumov-Gerasimenko with well-sampled time resolution per rotation, indicating a complex coma-nucleus relationship.
Journal ArticleDOI
Comparison of 3D kinetic and hydrodynamic models to ROSINA-COPS measurements of the neutral coma of 67P/Churyumov-Gerasimenko

TL;DR: In this paper, the authors present the first full 3D simulation results of 67P's neutral gas coma, including results from a direct simulation Monte Carlo method, a hydrodynamic code, and a purely geometric calculation which computes the total illuminated surface area on the nucleus.
Journal ArticleDOI

Jinbin Cao,C. T. Yan,Malcolm Dunlop,Henri Rème,Iannis Dandouras,Tielong Zhang,Dongmei Yang,A. V. Moiseyev,S. I. Solovyev,Ziqian Wang,A. Leonoviche,N. Zolotukhina,V. M. Mishin +12 more
TL;DR: In this paper, the authors used the plasma data from Cluster and TC-1 and geomagnetic data to study the signatures of the current wedge produced by fast-flow braking in the plasma sheet.
