The mineral, crystalline silica-made quartz, was found in a primitive carbonaceous meteorite
named Yamato-793261 (Y-793261).
These materials do not account for much of a carbonaceous meteorite's mass, but they are significant because they show that interstellar material is preserved in the present-day solar system.
A great advance in studying the formation and evolution of the solar system has come from the analysis of a carbonaceous meteorite that fell in September 1969 near Murchison, Australia.
For instance, a clear indication of the presence of both metallic iron and magnetite in the carbonaceous meteorite
, Novo-Urei, is demonstrated in Figure 1.
However, when researchers from Brown University re-examined the data with a different standard - a carbonaceous meteorite
containing organic matter from an asteroid - they were totally surprised.
Paper Title: Carbonaceous meteorites
contain a wide range of extraterrestrial nucleobases
The BAF hypothesis was bolstered by them being dark and with a spectral shape similar to carbonaceous meteorites
In this work, we consider [sup.36]Cl found in CAIs in primitive carbonaceous meteorites
in accordance with a solar wind implantation model.
Carbonaceous meteorites contain over 70 amino acids, some heterocyclic compounds, including purines, and carboxylic acids.
As noted previously, carbonaceous meteorites were also a potential source of purines.
might have carried water to Earth, Owen says.
The large-scale presence of organic molecules in the interstellar clouds, comets and asteroids, and evidence of amino acids in carbonaceous meteorites
support a cosmic perspective on the origin of life.
