CHO-bearing organic compounds at the surface of 67P/Churyumov-Gerasimenko revealed by Ptolemy
Andrews, D. J.; Sheridan, S.; Wright, I. P. +3 more
The surface and subsurface of comets preserve material from the formation of the solar system. The properties of cometary material thus provide insight into the physical and chemical conditions during their formation. We present mass spectra taken by the Ptolemy instrument 20 minutes after the initial touchdown of the Philae lander on the surface …
The structure of the regolith on 67P/Churyumov-Gerasimenko from ROLIS descent imaging
Bibring, J. -P.; Jaumann, R.; Mottola, S. +15 more
The structure of the upper layer of a comet is a product of its surface activity. The Rosetta Lander Imaging System (ROLIS) on board Philae acquired close-range images of the Agilkia site during its descent onto comet 67P/Churyumov-Gerasimenko. These images reveal a photometrically uniform surface covered by regolith composed of debris and blocks …
Old supernova dust factory revealed at the Galactic center
Morris, M. R.; Lau, R. M.; Herter, T. L. +2 more
Dust formation in supernova ejecta is currently the leading candidate to explain the large quantities of dust observed in the distant, early universe. However, it is unclear whether the ejecta-formed dust can survive the hot interior of the supernova remnant (SNR). We present infrared observations of ~0.02 solar masses of warm (~100 kelvin) dust s…
The nonmagnetic nucleus of comet 67P/Churyumov-Gerasimenko
Haerendel, Gerhard; Motschmann, Uwe; Russell, Christopher T. +17 more
Knowledge of the magnetization of planetary bodies constrains their origin and evolution, as well as the conditions in the solar nebular at that time. On the basis of magnetic field measurements during the descent and subsequent multiple touchdown of the Rosetta lander Philae on the comet 67P/Churyumov-Gerasimenko (67P), we show that no global mag…

67P/Churyumov-Gerasimenko surface properties as derived from CIVA panoramic images
Le Mouélic, S.; Bibring, J. -P.; Gondet, B. +8 more
The structure and composition of cometary constituents, down to their microscopic scale, are critical witnesses of the processes and ingredients that drove the formation and evolution of planetary bodies toward their present diversity. On board Rosetta’s lander Philae, the Comet Infrared and Visible Analyser (CIVA) experiment took a series of imag…
