Expand Your World

We are citizens of a little world called University. It is the core of our lives; we live and breathe its rarified air. Its sidewalks carry us from one gray building to another- from applied art to zoology, with stopovers at child development and economics. Its professors cram our little heads with facts and figures- vapor pressure at sea level or the number of raisins in one cup

Add a Jibber To Your Wardrobe

Start now to knit a jibber to combat cold winter winds. A jibber is an easy-to-knit cap which protects head and ears, and yet is lightweight and uncumbersome. It is about five inches wide at the top of the head, narrows to two inches under the chin, and is fastened securely by yarn ties to keep out cold air

On the origin and evolution of the material in 67P/Churyumov-Gerasimenko

International audiencePrimitive objects like comets hold important information on the material that formed our solar system. Several comets have been visited by spacecraft and many more have been observed through Earth- and space-based telescopes. Still our understanding remains limited. Molecular abundances in comets have been shown to be similar to interstellar ices and thus indicate that common processes and conditions were involved in their formation. The samples returned by the Stardust mission to comet Wild 2 showed that the bulk refractory material was processed by high temperatures in the vicinity of the early sun. The recent Rosetta mission acquired a wealth of new data on the composition of comet 67P/Churyumov-Gerasimenko (hereafter 67P/C-G) and complemented earlier observations of other comets. The isotopic, elemental, and molecular abundances of the volatile, semi-volatile, and refractory phases brought many new insights into the origin and processing of the incorporated material. The emerging picture after Rosetta is that at least part of the volatile material was formed before the solar system and that cometary nuclei agglomerated over a wide range of heliocentric distances, different from where they are found today. Deviations from bulk solar system abundances indicate that the material was not fully homogenized at the location of comet formation, despite the radial mixing implied by the Stardust results. Post-formation evolution of the material might play an important role, which further complicates the picture. This paper discusses these major findings of the Rosetta mission with respect to the origin of the material and puts them in the context of what we know from other comets and solar system objects
